Two small ideas I had, maybe you like them. Both are about the drawer gui:

• It would be nice if one could deposit/withdraw stuff from the current drawer within the gui
• I often wonder what the maximum capacity of a specific drawer is. Maybe this could be shown as text somewhere in the gui?

The slots are disabled because it's actually a hard problem to interact with them. Applied energistics basically rewrote the GUI stack to make it possible for their terminals. Displaying capacity wouldn't be too difficult though.

Don't bother with the gui interaction if it is too hard to program :-)

If I may... I like the capacity idea, and a simple "100/4096" would be more than sufficient. I do not think that would be redundant with the Indicator Upgrade II.
