- Release an official beta pack/edition.
	- Modpack of experimental features vs. alternate game by branch?

- Flammable/igniter ABM should be reversed, so we scan over few igniters
  instead of many flammables?

- Wandering fluids API for concrete, glass?

- AStMs: Active Stack Modifiers.
	- Operate on all visinv nodes.
	- Possibly operate on player inventories?

- Make separate walkable/non-walkable stack nodes.
  - Should sticks and eggcorns be non-walkable?

- Code Quality.
	- Scripts to validate dependency graph.
		- Tag deps directly in code at place of use.
		- Auto-generate mod.conf / depends.txt
	- Scripts for automatic metapackage mods?
	- Git hooks (and git hook setup scripts)?

- API Cleanup
	- Utils
		- Box mueller (and repeated box mueller sum) and exporand
	- Break up the nc_api monstrosity.
		- nc_api_base to create _G.nodecore and include for all.
		- nc_api metamod that just depends on ALL other api's.
		- nc_all metamod for 3rd party mod authors...?
	- Heat API
		- Unified heating/cooling number from env.
		- Proper API for burning up items
			- on_burn?  burns_to?
		- Unify heat transformations into recipe system with
		  cooking recipes?
	- Unify nc_items and visinv API.
		- Stack nodes are "special", get first-class support.

- Make neighbor/distance calcs consistent.
	- We're using scan_flood in some places, face checks in others,
	  and find_nodes_in_area (cuboid) in others.
	- Diamond shape would be most consistent.
	- Should require face touching, not diagonal.
