My girlfriend is playing as well, she prefers to play with a controller and it turns the UI into the same one on the XB1. Can you customize this on the PC?
Better UI has some really useful features like being able to search guild stores by a keyword and putting the trait at the top of the info window and telling you if you already have it researched. It completely changes the inventory and bank to be easier to navigate and use less room like the default UI. You can customize it a lot, each part of it can be disabled so if you dont like the inventory part just remove it and the rest still works.
It has a few issues right now the 2 most notable being the inventory size and your gold amount is not updated on the inventory menu you need to go to a vendor to find out accurate numbers. It will update after you log out though. The second issue is the error message that shows up when you try to link an item in the chat. To do that you have to disable the controller interface and do it with keyboard and mouse.
