TotalSpaces is a few days from 1.0 release, beta testing 0.9.9 now between Lion and Mountain Lion. It is FANTASTIC! Works exactly as Spaces did prior to Lion. Some screen shots attached. I use dual displays, support for dual displays is coming in the 1.0 release as well as other features.
Wow! This seems really good, how come heard much more about ReSpaces App, which is totally buggy? This seems like they're taking things seriously!
Too bad you now have to pay for something that used to be free though...
