If this works, can you make a grid inventory mod? I know that I, and many others prefer to see a grid where we can easily see everything we have rather than having to scroll through lists and even more lists, like in Morrowind.
Grid view is not planned. What good is it if you have 50 items per page but only 10 different icons, then you have to hover all of them to see if its the one you want. I prefer lists over that, plus it's much easier to pull off.
Still making progress btw

Recent changes:
- Fixed most issues. The scrollbar is still a bit wonky, and when using an item with E it jumps to a random list position. But besides that, but those are the only issues left I'm aware of at the moment.
- Tweaked keyboard usability. You can now scroll list pages with the page up/page down keys, and when no entry is selected, pressing up will start selecting the last entry, and pressing down the first. So this should allow intuitive and fast keyboard navigation through the lists.
- Added a little animation to the category indicator so it looks smoother
A first official release will probably have to wait until the next patch though. As I understand it, due to the issues with the last patch quite a few people avoided upgrading so far. But the interface.bsa changed, the two versions are likely not compatible, so we'd have to pick one.
