Welcome back, Steve. Welcome back, blog.

Question for readers: what is your favorite multiple-clipboard utility?

I got addicted to this functionality when using KDE for a couple months last fall. I've looked at a number of the OS X options, and for some reason I've become very fussy. I like the implementation in YouControl, but it comes with a lot of other cruft I don't need. CopyPaste is, I'm sorry to say, ugly (is it my anti-Windows bias that makes me dislike those over-saturated reds and blues?), which I can overlook in free software but not in payware. Keyboard Maestro Lite is free (always nice), but it is not smoothly integrated enough -- you have to choose between either regular one-step copy/paste functionality or the enhanced type with its intervening dialog and uselessly named clipboards.

What I want, most simply, is an invisible clipboard stack. When I copy or cut, the selection is pushed onto the stack. When I paste, the item at the top of the stack is pasted (and optionally removed from the stack). A simple selection window would allow for more involved tasks, like discarding items or pulling something from mid-stack.

What's out there that I've missed? In what ways can the existing tools be adapted? Could this be hacked up somehow using e.g. Keyboard Maestro invoking shell scripts that use pbcopy and pbpaste?
