Operator 0.8b adds a much requested feature - an operator icon on the location bar. It's not perfect yet, but it is there. Also, I updated the action API a little bit to allow for the naming of actions as well as having actions act on multiple properties in a microformat. For instance, in the past, the "Goto web page" action only worked for the first URL in an hCard. Now it will work for all the URLs.
The other big fix in this release was that there were cases where sorting/removing duplicates didn't work correctly. For action developers, I added the ability to have multiple translations of an action in one action. I'll document that soon.
All the caveats from Operator 0.8a apply, so please read them.
