Cool, im not playing atm, just keeping an eye here to support my mod, when i do though ill def be looking at your UI mod.
Tbh had more fun playing just to code more mods ;)
UI work was a limiting factor for my Minor Tweaks Mod, could only figure out how to clone buttons that existed already, and affect some already placed ui.
Changing the UI certainly isn't the most straightforward with the mod system. For my UI mod I went the direction of building the entire UI bar all by itself (and as a new/separate file). Then I modded script files to strip out the old components and patch mine into place. You could also do it by directly modifying the original UI, which would reduce a little of the patch work (although would still need to edit a number of things in the script to make it compatible). Going this route becomes a little trickier if multiple people/mods want to change the UI.
About your own mod, I have noticed it before and really like the keyboard navigation through the slave list in the mansion. Comes in quite handy. Also, the inventory sorting is a must.
Can not say I've hooked up things like mass spells or any of the export features though. I tend to play keeping spell usage almost exclusively to combat. Not come up with any use for the export either (I see you say you use it for the repeatable quest system, which certainly could use help. As it is I just ignore the quest system when I play.)
As you say, modding the game is a lot of the fun.
