I’ve been looking for something like TotalSpaces for ages. Looks amazing, and I’ll be buying it the next time I’m on a Mac.
But what would completely knock my socks off would be the ability for an “inside cube” transition option. ie. instead of looking at your spaces on the outside faces of a cube, look at them as though projected on the inside faces of the cube.
I can see how that would be cool. The transitions we are using are provided by apple’s libraries. At the moment we’re not sure what transitions will be doable on Mavericks, but if we end up doing our own we’ll try to include this one.
