Helps when you have a problem trashing a file or ejecting a disk.
Did you ever have the problem where you can't empty the Trash or eject a disk because something is preventing you? Usually the reason is because some application has a file open, and thus you can't get rid of the disk or trash the file. That's why we made What's Keeping Me! What's Keeping Me will identify the application that is preventing you from accomplishing your task. You can then use What's Keeping Me to quit, relaunch, or kill the problem application so you can get on with your business.
