2 things that would imo improve the GUI
I agree with 1., that option should exist.
2. should be an option in the hero panel, not directly in the UI or even a hotkey because that would be overused in WvW. The same option should exist for a second set of traits.
@Iruwen: The hero menu would indeed be a very logical location for such a button. In order to prevent abuse it would be an option to only allow people to swap kits:
1. Outside sPvP arenas/WvW battlegrounds/Dungeons, so that you cannot run a dungeon and constantly swap kits per encounter but must make a choice which one you stick with.
Or
2. Put it on a cooldown timer. So if you swapped around from condition damage to healing setup it’ll be another 5 min before you can swap again.
Both versions will force people to really think what they want to stick with, without taking away the improvement to the ease of use of customization.
I created my on thread on similar problem just now read yours

It is so fearsome, brutal and agile, that no one say it’s name out loud.
They are afraid of their wrath so just call them DeX. But the real name is Dexterity Overload.
