That's great to hear, and useful info if others have the same issue. I know the XP bar has given you fits for a while. If you saved any of the bad uisettings files you're welcome to email those to me and maybe I can figure out what was going on.
I'll look at #1 which sounds like a good idea, although bag titlebars are running out of space for players who use the default four-across slot layout. For #2, Enter To Accept
worked fine the last time I checked and Sigrdrifa plays currently so I'm sure it's up to date. Since it's a case of unzip and throw the files into DarqUI_v3 with no conflicts, I'd be hesitant to duplicate her mod.
