I have some screen shots up that show most of what you can do with it... I'd be interested on getting some feedback. It is written in php and I've integrated management for my SquirrelMail plugin amavisnewsql as well. Take a look... The mailstore.png image shows most of what you can do cyrus related... if you click on folder names you can manage ACL info for that folder.
This is a usable admin tool for me and our help desk staff... but it is still undergoing active development of features.. and lots of clean up and visual enhancement. This was based on a few previous tools that were around pre-registerglobals.. and the way some things are done needs to be changed.
