One of the many things that SWTOR did right (that others have as well) is the ability to save multiple UI sets. The most Optimized UIs for different archetypes are different enough from each other that compromising one single UI for the three makes things difficult, even if it is in a minimal fashion. I love the UI in this game, but there's no denying that a Tanking UI is different than a DPS UI, and much different than a Healing UI (when talking about optimized UIs, of course)

Should such an update take place, the only other thing I could think of to compliment this is to let us link a saved UI within a Gear Set. Change to your Tank and your Tanking UI appears. Switch to Heals, and the UI changes in suit. No need for extra menu access/ button pressing. One button and it just works.

If this has been proposed before, apologies. I searched the forums and couldn't find anything. Partly because the search function is abysmal.
