Small things:

- drag and drop action buttons to swap their contents (not currently possible?)
- animate button-down effect when it is activated through function Fxx keys (=> instantly notice error when pressing wrong Fxx key)
- auto_select (@selectedTarget) as the first creature in room option?
- separe eq/inventory/room window for items, allow drag'n'drop of item names between eq/inv/room, allow drag'n'drop to party members too
- allow adding special scripts/plugins to the menu when text is right clicked
(right click item/text/monster => select appraise/identify/take/kill from menu to appraise/identify/take/kill item/monster)
- at least mind development (psi spell) icon doesn't correctly disappear from spell effects area?
- allow assigning pictures to buttons from scripts/plugins
- make button bar similar to effects window (no frames etc)

Didn't quite get what you mean with this, can you please elaborate a bit?
