The icons ![commands](/textures/vbots_gui_commands.png) and ![inventory](/textures/vbots_location_inventory.png) are used to switch between the 2 panels shown here.
The panel above contains the commands for the bot, which can be added to the current sub-program (the red area on the right) simply by clicking on them.
The panel below shows the inventory panel, with the bot's inventory above, and the players inventory below.
This panel is used to add things to the bot's inventory (so it can build with them) or to remove things from the bot's inventory after it has been digging.
