Flycut is an example of great software that does one thing well and solves a problem that almost everyone has.  It is a clipboard utility for the Mac that allows for practically limitless number of ‘copy’ items to remain available for paste.  The standard Mac clipboard keeps just one copy item – each subsequent copy replaces it so it’s copy, paste, copy, paste, copy, paste often switching between windows or tabs of a browser each time.  Flycut is a small “resident” program that allows for multiple copy commands to be stored for later pastes in any order.
