I like and use the bookmark tool, probably too much. Bookmarks would be versatile if we could name them, categorize them, and/or add personal notes to them.

There is so much to learn I need someway of creating my "note cards" without translating the forums to paper... I just dated myself with debate note cards... it's how my mind works
