Additional slots are totally useless for me. I dont understand why i cant scroll to empty hands/slot ? Instead of this i always see something what obscure my view (weapon, painter etc).
Most time in game i spend running without any gadgets in my hands to have better view. So additional slots are useless, because i must drag them to inventory exactly as it was before.
My suggestions is to add possibility to scroll to "empty" hands - without any device.
ps. I found now this:
