Hey first off, thanks for picking this up :) We ran into a couple of issues we had pinged Deadlock about but he wasn't really interested in fixing them, and decided to offer up the mod for anyone who wanted it.
The biggest one is when playing with a mod that adds lots of sub groups, the tabbed pane display doesn't wrap so the tabs start to get really skinny. (easy to see with Pyanodons)
The second one is that when you filter with the search it doesn't automatically remove tabs that have no results.
Lastly, maybe more of a feature request (happy to move this into a separate issue), but more plates made out of more things (u235, titanium if you're playing FE+, etc etc)
Thanks again :D
