@FireLight: have you taken a look at the manual
The full SDK
is described there. There are also more and more 3rd party dev, as well as plugins and behaviors released in the plugins section
If you don't go to the developpers, it is unlikely indeed they'll come to you if you just stand in your corner.
As far as suggestion goes, not all suggestion are good, and there must also be a choice made in the priority of features to add to C2. It's not because a feature isn't implemented TODAY, that it will never be.
Also, it was clear from the beginning that C2 was aimed at HTML5 "against" flash and that an exe exporter was a possibility, not something set in stone.
Once again, only time will tell wether there is or not finaly an exporter.
Anyway, as long as the HTML5's one is not finished, don't expect it.
EDIT: Reading again your suggestions, some are trickier to implement than you think I'd say, and would require some massive reorganizing before being added.
For now Ash as already a lot of work on his hands, it's unlikely he could handle so much stuff at once. Give him time. Kyatric2011-12-12 19:44:18
