I like these ideas.

That said, the devs have said for some time, they are very, very limited in what they can do with UI due to the PS3 RAM limitations. They explained in the past, that simply adding things like new buttons to the interface was quite challenging as they had to do some acrobatics on the back end to make it so the PS3 could still display all the UI elements at the same time.

Once PS3 support is dropped at the end of Heavensward, I would expect to see a lot more QoL improvements in terms of UI.
