If there is a certain version of Drupal Core required to enable and use this module, then might I please suggest adding it to your project page so people know.

I am running Drupal 7.10 on a particular site, but installing version 7.x-2.3 of this module states its incompatible with Menu 7.10 - "Menu (>7.11) (incompatible with version 7.10)"

cheers
