I would like to add "Ditto", an open-source/freeware application that "saves each item placed on the clipboard allowing you access to any of those items at a later time" (from the website).
I've been using it for one or two years and don't know how I could have ever lived without it...
There used to be a portable version that would only run from a U3 drive (:o), but now there's a regular portable version, too.
Hope you'll like it.
PS: I'm new, so sorry if there's anything wrong about my post. I'm not sure this hasn't been posted before.
