Pro Make FN key into a new modifier key for custom shortcuts across apps
Pro Convenient and fast access to files and notes
Unclutter lives in the navbar at the top of your screen, and is always accessible. Any files and notes stored in Unclutter can be quickly accessed from anywhere, with just a mouse movement and scrolling down.

Instead of keeping commonly used files on the desktop, you can tuck them away to the top of the screen. This can unclutter your screen, or create more room for more icons if you like quick access to everything.
Cons
Con Difficult to configure custom actions
Configuring custom actions requires editing an XML file with very strange syntax, for which it's difficult to find good documentation.
Con Can't keep visor open when typing in other applications
The unclutter visor will not stay open when working/typing in other apps. Sometimes it is desirable to use the visor to re-type things, it's not possible outside of copying and pasting, or opening and re-closing the visor.
