I've tried this app for the demo period and will buy it now (especially since the price is currently 1/3 of the usual price).

What I want to see though is the ability to assign certain apps to certain desktops so that if the app isn't already open, I can open it and it will open on the appropriate desktop and not the current one. Currently what it does is to open any app in whatever desktop you are in at the time. The only time I want Safari (for instance) to show up out of it's desktop is when I manually drag the Safari window to another desktop. Also, the individual desktops remain open whether or not the software you want to show on it is open or not. So if I have one app open, I still have 8 or so windows to flip through. As well, my menubar is so crowded with Airport and battery and clock and such that the YC menubar rarely ever shows at all. I need switching in the dock or a custom shortcut to switch to each individual desktop. There is also nothing anywhere on screen (except possibly the menubar items that won't show up for lack of space) that tells what desktop is the current one so I must switch back and forth to see where I am because I don't want to open an app in the wrong desktop... It had one bug of multiplying one app from one desktop to all of them and I had to quit the app and restart it in the correct desktop. If it included all of these features and had no bugs, I would easily give it 5 stars.

Still it's a good start and I recommend it and hope that my registration money will aid them in improving and maturing this promising app.
