You’re engrossed in a project and suddenly get an urgent phone call from another client about a different project. It’s only a ten-minute job so you break off from what you were doing and do the work for the second client, leaving all the windows from the previous job open while you do so. We’ve all been there and all know what happens next: you end up entering data from the second client onto the first client’s spreadsheet, post on the wrong chat thread, and send an email to the wrong person.

When that’s done, simply click the “Task View” button again and go back to the previous desktop. You can even give them names, and have several desktops going at the same time. When the phone rings, simply select the desktop for that client or project. This is how mine looks (I wish):
