More than two years ago I wrote about a little menulet that I really like: Spirited Away. It automatically hides applications that you haven’t used in the last minute and so keeps your desktop decluttered. Unfortunately it’s already a bit dated. Nial Giacomelli to the rescue! He has written Houdini which also hides unused apps but, despite his company name Ugly Apps, comes with a much more elegant user interface and the ability to set the individual hiding intervals for each app. It’s free, check it out here.
