Just packaged up the a snapshot of the current cvs HEAD of tomboy which includes the cool new note pinning feature. It seems plenty stable, and imho a very useful feature.
I practically run my life through tomboy, and this has been something I have been wishing for. The idea being notes that you want to always show up in your list you push the little pin in… and it stays! Check it out, Foresight users just run “sudo conary update tomboy”.
