I don't think it requires a huge revamp, but I think that there should be spreaded categories for at least the following :
- Spells / Special abilities
- Potions / consumables
- Items (special use)
I honestly hope not ... i have seen few examples from moders, and other people trying to create some UI and they were almost allways ugly and kinda confusing. :-/
I admit that im kinda obsedant about my hotbar order, if game would force me to get use to their oder by separate categories on fix positions ... i dunno, it would piss me off constantly (simmilar to popup casting ... wich seem to stay, so i gues you have pretty high chances for implementing)
Dunno how about you, but i would like to see hotbar as it was in
first build ...
Almost 3/4 of screen at our disposal ... now we have barely half of that.

I wonder why.
You really needed to quote whole post? :-/
This should be concidered spaming. :-/
