Title: Pasteboard UTI

I don't know how I managed to find that out, but there's this interesting page (http://nspasteboard.org) which contains some remarks for clipboard managers. Since I feel concerned about private things showing up in the Clipboard History, I tried to bring our Pasteboard category up to speed w.r.t to transient or private data. HTH ;-)
