One nice little utility that I used to use but left it, as i thought it was abandoned is back: Notational Velocity. Its a very small an unobtrusive note-taking application that, because of its cool interface design doesn’t need features like tags, folders or categories, which is pretty remarkable.
The current version was brought up to date to support Snow-Leopard and has become open source.
Just one feature would be nice: the option to put it in the Menubar instead of the Dock as it feels more natural for an Application that is almost always running in the background (like ShoveBox does). But that doesn’t stop me from using it for now. Nice.
