Thank you Jack
I'm sure multiple workspaces are going to change the way we work with many of our images, especially for complex processing procedures.
Tomorrow I'll upload a small tutorial on workspaces to show how to use them with all the mouse and keyboard tricks. however I think they are quite intuitive. For example, just drag an icon over a workspace selector (1, 2, 3, 4, ...), then move it to the workspace and drop it; now it's on the new workspace. Isn't it easy?
Enjoy!
