Thank you for constantly working on it. I want to say your UI plugin is prob the only one that's approachable and reasonable for everyone to use, with ease. Managed to get most of my menus right, thanks to you. 
I want to showcase 2 scenarios (the only two left in my case) I struggle with. First one, is ITEM-use and MAGIC use (both out of battle, in their respective menus). Before the update, it wasnt too bad. In fact it was the only flaw I was accepting (a foot backward) my game would be stucked with, as bad as it was. Let me show you (before update 1.2.1). As you can see, its not ideal...
Now this is the results of updating to 1.2.1. Ouch. xD 
Okay, my second point. I use (as you can see above and below) a plugin for hand cursor. Your plugin necessitate careful balancing of size and margin, for it, as otherwise you risk clipping in SOME menus (even in-battle). I got it okay, I think. But see, if you go in a shop to try and buy you get the hand covering the numbers. xD Now you could argue its my fault for keeping the hand this big, but I made it this way so it would look best in the main menus... Let me show you what I mean below. A solution I'll try is finding a SHOP plugin which circumvents this with extra margin rules. Ill test a few. 
Thats about it. Stats/skills are all nonsense for now, as its a thing Ill work on at the very end. Edit: One last thing. I got a plugin from ATT_Turan on the forum which allows me to see max values (like one of your update provided (TY for that)). Only, on that one's end, it doesnt squish numbers on item/status menus. Would you like me to share it with you?
