Is there no one who can take up this project?

Indeed. I’d like to see someone take this up, or make/find a plugin like it!
Please share ??

Michael Officier, WP-cirrus is the only one I believe!
I have requested some features in a review of their plugin. Lets see if the authors are upto it. Looking at their plugin, they appear to be sportive! ??

By the way, Wp-Cumulus still works on WP3.5.2. Only the color changes are not working and i am trying to work it out by changing the plugin php file default options. See following link for info.
