- Visual "subtitles" for sounds?
	- Use new image_waypoint HUD type; it works in new versions,
	  invisible in old versions (graceful fallback).
	- An icon for each sound type.

- Separate air vs. node cursor?
	- Like the node vs. entity cursor, can we hide the cursor when
	  pointing only at air?
	- Would server lag be too much?
	- This would integrate really well with a WAILA sort of thing.
	- Could totally revamp touchtips, and dynamic feel Lightning.
	- Use an image HUD so we can force mobile to display it too, so
	  mobile players can use look dir too?

- Buff igniting
	- Make hot lode and other heated materials able to ignite
		- This was probably not already done just because we
		  didn't have AISMs at the time, but we do now.
	- Reconsider lux fluid ignition again.
		- Maybe have rare "spark" events that can ignite?
		- Maybe have it involve proximity to other materials?
			- Water? Lava?
			- Optic beams?

- Chop frames, ladders, staves back down into sticks?

- Can we use glasslike_framed for shelves?
	- Alternate 2 versions of the registration based on y coord
	  so it forces top/bottom faces to show

- More lode bar crafts:
	- Frames
	- Ladders?
	- Adzes?
		- chop+crumb -1 relative tier
		- cracky -2 relative tier
		- full durability
		- Should these be full lode or wood handle?
	- Rakes?
		- Return some prills after construction?
	- Make wear carry across heating/cooling recipes
		- Allow full-lode tools to be tempered
	- All these need to be recyclable.

- Piezo node for optics detects sounds?
	- Sounds emitted by mod stuff?
	- Footsteps?
	- Can be used as a BUD

- Lode tongs?
	- Craft from bars/rods (or lode adzes?).
	- Add an API to hot potato
		- Scan for all hot potato items and produce a list of slot->bool
		- If any items found with an on_hot_potato callback, pass them
		  that list (and player, inv, etc) to be modified.
	- If slot is marked "safe" then no hot potato if items are in
	  a slot adjacent to tongs.
	- If slot is not marked safe, mark it safe if tongs or any tool
	  are wielded item.
	- Unmark safe any slots that don't contain hot things after
	  hot potato check.

- Allow frame loose ends to be chopped off when placed next to other
  frames, so custom shapes can be made.

- Dungeon loot
	- Add recipe hints (prearranged nodes) as decorations?
	- Rows of shelves against walls.  Very rarely lode crates.
	- Loot items in shelves, weighted pickrand().  Add a "margin" pick
	  result with value of proportion of where in range the picked value
	  was, and vary tool durability or stack count non-linearly by it.
	- Scattered items on floor.  Most are from loot tables, some are
	  crates or storeboxes.

- A lode "mace" tool with all dig groups?
	- Would require reevaluatng recipe priority, or tool modality.

- Make lava easier to find at a distance visually
	- Particles, like cherenkov?

- New Darkness feature:
	- Keep track of queue of recent "safe spots" for player:
	  in sunlight, on solid ground or climbable etc.
	- Also check for being completely entombed in solid non-climbables.
	- Track player darkness, search for nearby light.  Keep track of recent hit/miss (ring/queue).
	- If player is in TOTAL darkness for long enough to be certain, then do "fugue" teleportation.
	- Fade screen to black slowly via HUD (maybe have an API for this for skyrealms).
	- Drop all items.
	- Apply a temporary debuff...?
	- Teleport player back to recent safe spots until we find one, or run out.
	- Fade screen back from black.

- Should tool appearance vary based on wear?
	- Make "fresh" vs. "worn" tools (for purposes of their usability
	  in crafts) have a distinct look?

- Tree sap
	- Stumps with air above exude, become dry stumps.
	- Use as a glue/resin in recipes.
	- Make longer-life torches?
	- Stick optics in place to prevent rotating?

- Straw/thatch?

- Domain Wall Sensor
	- Adapt from sztest?
	- Field Generator?
		- Power an annealed lode block from 2 opposite faces.
		- Generates particle effect at mapblock boundary.
	- Particle effect with lux fluid and/or cobble?
	- Create particle effect around player while carrying lux in
	  inventory?
		- Maybe only if the lux is higher activation tier?

- Should ash and derivatives have a fertilizing effect?
	- Maybe wet/tacky stuccos?

- Optic locking
	- Prevent accidental rotation.
	- Use tree sap / glue?
		- Make "glued" optic node?
		- Detect adjacent glue node?
	- Apply frame, make framed optics?
	- Hammer into place with certain tool?

- Door Automation
	- Press tools (or tool heads) into nodes to activate other
	  pummel recipes like chopping.
		- Mount tool heads on frames to make machine tools?
	- Press recipes for digging.
		- If pushing a node (or toolhead backed by node) and there
		  is a climbable walkable behind it, or a storebox, dig the
		  node and push it through climable as catapult, or into
		  storebox if it fits.
	- Need more door materials: lode, glasses

- Renewability Gap
	- Renewable but not generatable
		- Sponges: Sprout under water from peat+sand?
		- Lode
		- Lux
		- Water sources.
	- Sustainable but not renewable
	- Not sustainable
		- Lava sources.
			- Surround stone with lava to melt?

- Threats
	- Visceral
		- Flammable/toxic gas?
		- Monsters: stone-lurkers, mimics.
			- Complex multi-node mimic that eats tools you try to dig it with,
			  stores them in core node(s) inside somewhere to be recovered.
		- Lightning, meteor strikes?
	- Creeping
		- Cellular automata hazards.
		- From exploration, delving too deep, leaving things to rot, etc.
		- Blights, Fungi
		- Termites, carpenter ants, other wood-eating inflictions?

- Lurk Ore
	- Moves freely among air-exposed stone while no player is looking.
	- Follows after player, attempting to cause harm.
		- Weakens nodes above/below player into falling nodes,
		  e.g. loose cobble, gravel?
		- Steals items from player, drops onto ground or absorbs them
		  into body?  Saps tool durability?
		- Ignites flammables it passes by?
		- Downgrades or absorbs ores nearby by contact or air floodfill?
		- Creates illusionary nodes you can fall through?
	- Cannot be dug or damaged directly.
		- Digging it yields plain stone, but converts up to 2
		  surrounding stone nodes into Lurk.
	- Need to dig all around it so it cannot move, then apply Some
	  time-integrated process to convert it to useful form.

- New materials to craft with.
	- Dungeon materials, stonework?
	- Decorations for dungeons
	- Small plants? Reeds? Mallows?
	- Sea stars, anenome, coral, other underwater things?
	- Fungi, esp. tree-destroying ones, blight?
	- Oil, natural gas?  Fossils and fossil fuels?
	- Geode, hydra crystals, radioactives?
	- Shipwrecks or alien tech
	- Slow-moving animals? Snails? Miniature spice worms?
	- Non-portable things, like "spawners" or wormholes
	- Tubers and taproots, cacti, and other "defensive" plantlife
	- Plant-like CA animals, like bee nests and clouds of bees?
	  Termine mounds? Ant colonies? Coral?
	- Popeggcorn?
	- Ores that smelt via heating and then rapid quenching?
	- Things that cannot ever be dug, and must be moved only
	  by in-world machinery?

- Vary player walking speed based on nodes under feet?

- Visual "craft guide" system?
	- Build a 3x3 work space out of wood/logs, place center node
	  last and it will convert to a workbench node.
	- Workbench node will scan for potential recipe matches
	  centered on the space above based on what's present
	  and matches at least 1 non-air node, picks one.
	- Create display "ghost" entities representing items that
	  can be placed to complete the recipe.

- Should tree growth rate start out faster but slow down?
	- This could make the decision to harvest trees early vs
	  wait for them to mature more nuanced.

- Social features
	- Randomize player appearance/colors.
		- Shirt/pants, possibly w/ stripes/patterns
		- Skin color, hair color, eye color?
	- Add a "cloak" layer for cloaks, capes, over entire body
	- Make some control states / anims last a little longer, e.g.
	  extend mining or waving anims to a second or so to make sure
	  they're visible and not just flicker.

- Drop-in recipes, triggered on thrown or falling items settling?
	- Good for dangerous stuff, maybe?

- Compact signage via concrete/writing/stylus
	- Draw glyphs on a wall.
	- Place a lens focusing light from the wall onto a spot.
	- Put pliant concrete in that spot.
	- Make sure wall is adequately lit.
	- Etch the lens-facing side of the pliant concrete with stylus.
- Create a "custom patterned" concrete sign block with letters etched
  onto it.  Store in metadata, use ents to render, etc.

- Allow metalworking with wood tools?
	- Eat a lot of extra durability?

- Door animations.
	- These need to be relatively efficient, i.e. not involve
	  a ton of node manipulation or spawning lots of entities.
	  Of particular concern is network packet load on clients.
	- Something using animated entities (which could represent
	  multiple nodes sharing an axis) could work well.
	- Alternatively, a reasonable particle effect?  Something
	  abstract is fine too, as long as it conveys a sense of
	  movement to help players visualize what's moving and in
	  what direction.

- Visual in-world hotbar
	- GreenXenith's visualbar mod
	- Replace hotbar, merge it with both bandolier and YCTIWY?
	- Players could be "pickpocketed" during normal gameplay.
		- Make a sound/visual to warn player.
	- Jordach's new first-person-attached entities feature?
