Finally, I've created extension that I might be actually using!

The name is Easy User CSS and I think it tells a lot about it's functionality. Before this extension you had to create new file for every site where you wanted to have user css.

I've just uploaded new version of Mini Google Maps extension to addons.labs.opera.com that should work in O11 final. If you will find any bug you can report it here in the comments.
