Great plugin, gets my recommendation.
Just wanted to report a slightly circuitous bit of UX which could do with some attention....
If you already have Adminize set up, and later register a new post type, it isn't included by default in the 'Menu' section Adminimize settings screen.
In order to include the new post type, I had to export the data, delete all the database entries for the plugin (via the button on the bottom of the settings page), deactivate, reactivate, and then re-import the data.
Hope that helps someone.
