I ran across PatternTap.com about a week ago and have been using it to manage and UI design elements. It’s a very handy tool for any designer – it mainly targets web design but graphic and print designers will find it handy as well. 

I offered a suggestion that would allow me to use PatternTap on a constant (as in hourly) basis: a FireFox plugin or a bookmarklet that I could use to highlight some features on the page and then contribute those features under the appropriate category. They responded quicly and told me that they’re working on that – I can’t wait.
