Planning to built it FOR SURE... I think we all need to wait until the next ClassiPress version lanched in order to keep this as a brainstorming in the forum trying to get more supporters who really love ClassiPress and have enough knowledge to make plugins, mods, childthemes, tutorials,etc...
If not possible to get more people maybe I'll prepare this more as a personal project if I do not find support from some other developers. Now I'm sure you and Mr Green are interested
so we can start doing this together little by little. Make it as an excellent childtheme (the best actually) for the one and only
(ClassiPress) as an excellent incredible showcases directory + plugins/childthemes market place.
