Heh, I was just about to make a post about this exact same thing. It wouldn't be so bad if the information from the infocard was actually displayed on the little panel at the bottom. But that this panel actually displays less information at a time when you're more likely to need it is a little silly.
On the topic of unit UI improvements: It'd be nice if the UI remembered which tab you have open when going from one unit to the next. So for example, if I've got the items tab open so that I can transfer an item over, I'm going to want the items tab still open when I select the target unit to equip it.
Also, combat speed. For a stat that seems rather important (or at least significant enough that it isn't neglected), it literally isn't displayed anywhere? Anywhere that attack and defence are displayed, combat speed should be visible also.
