A Features I would love to see added are secondary weapons slot and a switch icon. It could work similar to how it worked in Kotor 2, where you have 2 diffrent on-hand and off-hand slots that you could switch between, in and out of battle. It could cost 1 action point to do, similar to how in kotor 2 swapping weapons took 1 round. This feature would make playing a rouge/ranger hybrid, or a mage that uses different element staffs (also please buff the staff of magus ability; staffs feel vastly inferior to wands right now) a lot less of a pain, because you don't have to spend so much time fiddling with your inventory screen.
Another thing I noticed happened alot (in DOS EE's Bracus Rex fight especially), is almost suffering a party wipe due to aoe at the start, and then I have to force the party to split and go off in weird directions so that doesn't happen again. Rather than nerf these abilities, i'd like to see a setting where you can dictate how close your party members are to each other, in-addition to multiple formations like in DOS1 and DOSEE.
This would also help with trap detection, in that when the leader off the party discovers a trap, the A.I has enough to register that its there and walk around it properly
