Currently, health and energy potions can have their own keybindings outside the skill bar, saving you a (sometime useful) slot. However, there is no way to track their cooldown unless you also bind them to a skill bar key, which can be troublesome.
At least for health potions, would it be possible to add a status icon akin to that of Menhir’s Will or Deadly Aim, which appears after activation and remains during cooldown?
I put the icons on potions on 7 and 8 (nine and zero bound to up and down mouse wheel). If it weren’t for nullification effect, I wouldn’t need this at all. Even as it is I don’t need it often. You get at least 11 slots if you use force move instead of skill. Minus potions, 9 slots for skills. That would be plenty if I didn’t try to keep my buffs on the mainboard in case of nullfication. Sometimes I remove the energy potion to make room.
