Thanks a lot for the post about my plugin. I work on a new version, rewritten from scratch. Over the time the plugin was extended the plugin with much requirements and his solutions. But the source is not easy to maintain for me, I'm unhappy with the source. I have learned about coding, architecture etc.

Currently I search for developer there will help on dev and support the plugin. The plugin have a github repository to easy add a issue or a create a fork, pull request.

Especially the functionality for WP Multisite is currently more a hack as a solution. But is very complex, not easy to create a solution for this.
