I dunno if it's been recently posted on, but I'm not using the search function on this forum. :P
How about some quickslots for control setups? It'd be nice to switch from my standard swordsman control scheme to a gunner scheme, or even to a properly setup gampad scheme. Make it client-side, so it can be editable out of game, since control schemes wouldn't have an effect on any sort of server-side content.
Find the control configuration file in the Spiral Knights files and make a copy of it...maybe that would help?
