1. The biggest problem is that it unequips gear like scanner, mining tools etc, it swaps back to my gun when I press LMB/RMB after melee. Before rework I could just kill any enemies bothering me in melee and proceed to mining, fishing or whatever, but now I have to manually re-equip my tools every single time.
2. It hides ammo counter for my currently selected gun which is a bit annoying. I'd like to check if I need to reload my gun or if I have ammo while fighting with melee.
