It worked ok for a day or two. I then launched it for the next couple of days but the interface was always frozen. Without the freeze, i would have given the app 3 stars. It worked. It had problems but they could be overlooked because it worked. Maybe there was one. One problem. The saving was not silent in the background. The auto save interrupted my Adobe Illustrator every 5 minutes. The path I was making would be interrupted and unselected. I'd have to reselect the path to continue the interrupted work. Because the app was frozen for several days straight and never regained life, I cannot recommend using it. It does work for at least the first day.

How does this handle saving files that are being worked on - i.e. I am working on a Photoshop file, saving manually as I go. Does SC save anyways or only after an idle period?

How does the auto-save ensure you don't overwrite a file as you are working on it? Say for example I am working on a text file and accidentally delete an entire paragraph, then SC auto-saves.

Some sort of versioned Save As feature might be handy for this. Save As files could be named like: document 01- autosave 2009-01-29 4:31 PM.jpg or something similar.

I love the idea, but would worry that I would auto-save unwanted changes without a way to undo.
