Everybody please reply this post or write to feedback form, if there's major circuits that need to be added.
We have now more than 200k registered users (and plenty more unregistered). The track library review queue is full of personal test tracks, "touge" tracks etc. Proactively sorting through the queue for real circuits that could be added to the library is really painful now.
So most likely some major tracks are not going to be added before I write some better tools. Or get a kick to my behind to add it. 😃
