In my opinion, it would make TotalSpaces better if we could choose to assign an app to more than one desktop instead of just one or all. For example, I use Stickes notes that float on top, and now have them assigned to all my nine desktops. But I would prefer to only see the Sticky notes on five of them. This could be solved by having a checkbox next to each desktop number for each Application in the Apps Preferences.
That is a nice idea, and might be possible if TotalSpaces were to take over the handling of this from the default mechanism in the windows server. But it would be an awful lot of work to do that, so please don’t hope for it soon.
