Does anyone know if there is an addon that would behave similar to.....

The presets that each toon currently has for which addons load when you log in.
Is there a way to get say multiple presets for the same toon?
That way when I'm going to PVP i just log out, enable my pvp addons with one click then log back in, like wise for PVE, auctioneering days, etc.

I use Addon Control Panel. It is an in-game addon enabler/disabler, so you don't have to logout each time you want to load/unload an addon. Think I got it off Curse. It also has the ability to save sets and then all you need to do is reload ui and then the set will be loaded. The menu plugs into the "esc" menu with keybindings, exit game, video options, etc.
Works great.
