I love Konfabulator. It helps me in some way, every day from weather to just about anything I have downloaded (notepad, calendar, etc.), its awesome.

One thing I don't like about it is that it is a bit funky remembering which widgets you have open or not when you add new ones. It seems that when I restart it after opening then hiding a widge I newly downloaded, it comes back. I don't know if anyone else has been having this problem, but it is a bit confusing - maybe there is a trick I don't know?
