I like the plugin and have used it in the past, but it seems too unstable to be usable now.
The delete button doesn't work to delete a redirect. In fact, none of the options under the listings work. There are also other bugs when installed in 3.5.2.
At random times all of my groups will disappear then reappear.
After clicking a menu item, instead of a popup (at least I think that is what is intended), I lose all wordpress menu items and the screen only displays three rows of text/options. The latter consistently happens when I click 'edit group' from the group menu or 'edit' from the module menu.
Clicking a hit brings me to a page that says insufficient permissions sometimes.
