I created a new version of backendpro for codeigniter 2.0 i did this by making it php 5 compliant changed the modular extensions library from matchbox to hmvc, created additional classes and created the sessions database table to comply with version 2.0 of codeigniter. The beauty of Backendpro is its use of the nested sets model making it similar to the most popular php ACL Library PHPGACL. I plan to add other features that is why i call it backendmanager you can get it from here
