tomsstudio Wow, as the others already mentioned, WOW! I've got a vuvuzuela specially used to root for you!
As someone who has tried GM and Unity many years ago, and left because of very poor programming skills, I am not really that qualified to talk much about this. But perhaps Scirra could implement something where some of the updates can be voted by the community?
For example, Scirra could put a small list of new features for the next stable release, and let the community discuss and vote on which they would like to see implemented first. And maybe even a section for larger features that take a longer time, so at least the community knows that it is being addressed. The advantage of this is not only does it get all of us working more closer together, but it could actually help Scirra bring these functions to life earlier. For example, if everyone votes to have a native exporter for mobile, than someone might have also been working on something similar, Scirra and the person could work together for a short while to complete this instead of starting from scratch ( hint hint....tomsstudio's project!)
Of course, only Scirra truly understands the structure and how C2 is put together so some things need to be done and fixed before others can be implemented, but maybe it would be a positive thing to also let the community who are the customers also have a say in what they would like to see.
