There have been many improvements regarding usability over the years with a glaring omission: windows. It is very difficult trying to do things, like changing gear or digging through the bank or reading tasks whatever because window focus is non-existent. I could have my bags open (using the hotkey to open all bags), then use the hotkey for inventory, but my inventory window is buried underneath somewhere. I then need to move stuff around until I can get an unhindered view of the Inventory window and then proceed to do whatever it was I was trying to do. I don't know what the best solution is, but one thing that could be done is when a hot key is used to open a window, that window gets focus and appears over all of the others. Based on the existing behavior, there seems to be some sort of hard code precedence/handling of windows and which will appear on top versus underneath. Having a focus applied may help some. Window docking would be helpful too. We could dock bags, chat windows, etc into groups and move groups around to make things easier to manage. This is a big frustration factor with the game and probably a deterrent for having more players actively engaged. Not an exhaustive list, but a starting point.
