Dont know if this was suggested but here are my suggestions.
-Add in game stats when you are doing the run, like I pick an prob chance to crits, show it somewhere wich % I have.
-Customize UI, or at least let us move it, because for me on 1080p I feel that is too much near the center of the screen. Would be cool to move some parts more to the corner.
-Hability to see the challenges in game and objects too if not better add to the description when you pick the item, the stats and stack of the item. And maybe lock on challenges like quests when you are playing.
-Now that drones can be rebuyed, at least leave a mark where they die, at late game its impossible to see where are they. Plus I often confuse heal drones with rusty boxes.
-As an option, because maybe some ppl are used to, but want to keep running my char after the dodge skills like comando or hunter blink
-Test level, with all objects to test how they work and if they are worth it for some classes.
