To start off, I have a dual-monitor setup at home. Way before 2.1.0, I was using MoveAnything to customize my screens. My bags, quest log, character sheet, bank window/bank bags, social windows have been moved to the right monitor, while the main game screen was on the left together with my other combat-related thingies.
I have also moved the zoning text, mini-map, buffs/debuffs, alliance/horde flags and other items to the left monitor.
Everything was going fine (well, except for the occasional "jump" of the alliance/horde flag back to the default, but it's easily remedied by a /console reloadui) until 2.1.0, where almost all of the movable frames would either pop up as errors or would simply not move any more -- no frame to resize/drag even!
So I was thinking of asking to request an addon that could move several frames for a cleaner layout.
I don't know if there are any possible alternative/s addon for MoveAnything out there (if there are, kindly post the addon names so I can check them out for myself)
While personally I've been more than happy with MoveIt replacing MoveAnything, and probably won't switch back, I did notice that MoveAnything has apparently been updated to work with the latest versions of WoW:
