don't know if anybody mentioned this already, but i highly recommend and miss keyboard shortcuts.
what have they been for XCOM? edit: i think i've meant "jagged alliance" or another game like this...
like a for aim or sth...
i made a few thoughts especially about firing modes:
a for aim, a again for toggle through fire modes (nice to try out how's the percentage of hitting a target)
x for reactionary fire, x again for toggle through reactionary fire modes
i'd also love to see some more keyboard shortcuts throughout the whole game, like visiting different bases on geoscape or when equipping soldiers to assign different weapons or especially the camouflage design (or perhaps at least an "assign to all" function)
i think that'd please a huge amount of XCOM round based shooter fans... in that former times we used to use keyboards excessively, if i remember right :-)
disclaimer: i'm just downloading the 2.5, perhaps there have been made improvements... my ideas base on my experiences with 2.4
