My dear friend, our beloved Xenforo crew already have their hands wayyyyyyyyyyyyyyy full with developing a spanking brand new and innovative forum script which hasn't even turned one year old yet AND are dealing with a most annoying and irritating lawsuit. I think you'll find most of us more happy with them focusing just on Xenforo for now and then perhaps look around here and there once they have Xenforo up and high where they want it to be.
Instead of one script that contains all, I'd rather see them making a separate script for every functionality, forum, gallery, video, blog. I think it's bad to make one big bloated piece of software that contains all but does none of them right.
I started with these scripts when PHPFox 1 came out. I hate to say it, but IMHO virtually all of them still suffer from missing the essential drill down and functionality that best of breed scripts use, especially Social Engine, which started out with a tremendous amount of promise. Perhaps others have tweaked it to be more on target than the demo.
I'd prefer XF remain as the most fun, easy to use forum/discussion software that will eventually have complete add-ons and extensions that can be created by developers to enhance functionality, if desired. After all, 99% of the posts people usually make are in the forums, not in unused blogs, classifieds or polls.
