I'm not sure how difficult this would be; but, it'd help me greatly if a piece of equipment is assigned in the Quick Change feature, then that piece of equipment had some kind of indicator in the backpack. Like a little red dot or … I don't know, nothing fancy just something that when I go into my backpack I can easily see that a piece of equipment is currently assigned to a Quick Change.
This isn't something I think we'll be able to do, at least soon, nor can I promise it. Basically the way that they do the UI utilizes Scaleform, which is derived from ActionScript and Adobe Flash, and it's a mess to work with. It is also why there is such horrible performance for Dragon's Prophet in many cases. We can do some things, but adding new things may not be easily done.
