Something similar is Tooggle. File is on wowinterface. It has a hotspot feature as well as ability to toggle sets of add-ons and swap them. I usually use this to swap things like omen (in combat) and assessment (out of combat), hide SL Timex and chat frames as well as hiding a utility Bartender3 bar with things like hearthing.
I use the lua scripting in ee panels to auto hide things like the utility bar when entering combat, and to auto switch to omen on combat and switch back out to asessment when leaving combat.
