While it doesn't relate to OMJ specifically...I do like sharing with OMJ's following.
I came across a cool widget that is free. It puts 4 icons in the space of one. So you can group, etc.
It's called Multicon Widget and it's on the market. Comments say the dev is working to add folders, shortcuts and mini-functions to its capabilities in the near future.
