Mac: Desktop Groups, which is essentially Fences for Mac, is a great tool for keeping your desktop organised by allowing you to create new desktop setups on the fly. Today, it's on sale for just $1.99 (usually $8.49).
Desktop Groups lets you create different groups of files on your desktop for different projects. So, if you want a set of files available when you're editing audio, you can set it up so only those files are visible when you're working on it. Desktop Groups is a great way to declutter and clean up your desktop. It's on sale for $1.99 until Sunday, May 12.
