Great mod, I really look forward to seeing the rest of the UI comparably overhauled. You might want to include uninstall and update instructions in your readme/description page though. I had no trouble just uninstalling 1.0 and re-installing 1.1 via NMM, but it wasn't exactly clear whether that was all I needed to do.
Well, there isn't really anything special to do when uninstalling, so the instructions would be pretty short. But since the question has popped up a couple of times, might be good to mention it in the description.
As far as progress goes:
The magic menu itself is in place and working, now we just need more data to fill the columns with (spell damage, area, duration etc).
And container/barter... mh this is gonna be a bit trickier because we have to find/decide on a layout.
The easiest solution would just be to make some kind of tab or button that allows you to switch between the two inventories.
But then we have the itemcard and the 3d icon take up the whole right screen side, while we have to squeeze in everything on the left side...
I'd like to have a Fallout-style split view, so you have two inventory lists next to each other. But then the question is, what to do with the item card information.
So if anyone has any idea as to how the container view should look like, why not make a mock-up and post it (or just describe it verbally). It might inspire some ideas.
Edit:
My best idea at the moment would be something like this: http://i.imgur.com/CIrOt.jpg
So 2 columns at the top. 3 columns in the middle. The itemcard/3d icon column would of course be smaller (by 25%-50%).
