Software Invention That The World Needs

OK all you code monkeys, here is something that is needed -- a software invention -- Annotable Text on a Directory Folder.  Calling Microsoft and Mac and Linux GUI coders.  When I examine a folder on my computer, tablet, etc, I want the capability of annotating the folder.  I want to mark it as read, or vetted or junk or whatever.  I want the capability of adding a note to the folder without changing the name of it, and the note travels with the folder.

This is something that could make your name as a coder.  I am too busy to do this, but someone needs to do it.
