PTHPasteboard – mac software for download at iusethis:

A good friend of mine turned me on to Pth Pasteboard and I couldn’t be happier. At first, the idea of multiple pasteboard’s didn’t seem helpful to me, but after I started using it, I started realizing how frequently I was typing the same text over and over.

Another invaluable feature of Pth Pasteboard is Pasteboard Persistence – copying to your pasteboard becomes the same as saving! Unfortunately my 17″ MBP has never been as stable as my trusty old 12″ PowerBook was – every few weeks I’ll get a crash, but it’s amazing how frequently the data that I was so worried about loosing pops up on the pasteboard on the side of my screen!

Once you’ve been using Pasteboard for a while, you’ll also find the text filters to be quite useful – especially for fixing up junk text that you copied from an email and need to forward on. Note, Pasteboard used to look a bit fugly, but the author recently added Anti-Aliasing – blends into the system quite well.

Give it a shot – I think you’ll really enjoy this one!
