Many users asked for a TotalSpaces that displays all windows at once, instead of stacked as it’s been since Lion.
Unfortunately, we can’t commit to doing this right now because the big job is porting TotalSpaces to Mavericks. Once we get a handle on how much can be moved to Mac OS X 10.9 Mavericks, and what new features might be added, we’re not sure about having all-window Exposé.
Thanks for your patience.
