ArenaNet:Guild Wars 2 suggestions/Interface Preference Saving

Saving Interface Changes (Discussion)
A option to save any changes to the Interface and Control Options(hot keys) so you can switch back and forth when needed. A Load Interface and Controls option would save time of changing all the keys and moving the interface around when doing PvP and when having to do something like Hero Fast Faction Farm which needs a different hot key functions to control all the heroes separate skills all the time.


 * Why this is a good idea
 * Faster and Easier transition between different interface and hot key preferences.


 * Why it may not work out
