in my ideal world the "quickbar" would be a submenu on a very minimalistic UI
Sounds awfull to me. :-/
Yeah, but it's not a problem of the UI, it's just you.
I mean, you described your ideal Ui here:
https://forums.larian.com/ubbthreads.php?ubb=showflat&Number=825596#Post825596Made out of very long hotbars, with several spells of different levels mishmashed on a single bar according to your individual preferences, "all your items ready to click there", etc.
And there's nothing that I can say except that it sounds like pure UI nightmare fuel to me.
Worst, it's a "build your own UI" set of pieces that needs to be constantly tweaked, updated and refreshed.
It's basically a typical super-busy MMO interface, except worse (as it "even less flexible").
Well, pretty much what we already had, in fact. Except for the recent updates to it that made some of us see some pallid light at the end of the tunnel.
