Look and feel wise, the UI is fine in my book. scaling and moving can be a low priority for all I care.
But, what really, really, really bugs me more than sitting on broken glass all day would, is the fact tha every time a companion returns from a mission, all the UI windows I was currently working in close.
If I'm on the GTN checking out mods for items, and I wanna compare that to whatever I have in my orange gear, the GTN window closes.
Seriously, I understand that it is beneficial to automatically open invent when you ctrl+right click to modify an item so newbies know what to look for, but it is also anoying as heck!
Not being able to layer UI windows is also a pain in the backside!
I have now taken to screenshotting items cause it's easier to alt+tab out to check the screenshots than to do it ingame! That should tell you something!
