I think Ribis what is trying to say, is why scirra gave more priority to features that not everyone will use at list very often, because the heavy job for development of your projects will most of the time done on PC, laptops.
so why not give priority to the most crucial futures that every single one needs like Easy exporters to mobile and more stability in mobiles.
This is the frustration that most of the C2 users are facing right now, that's why you see everyone is going nuts on the forum.
Most of the developers were waiting for C3 for a long time, to see if they will address this problem first. that's why you see the opposite reaction from C2 users, instead to been celebrating the C3 news they are disappointing and I agree.
The development on phone, tablets is really cool feature to have and will be handy some times, but what's the point if you can't start to develop a game for mobile because of the trouble you go thru to release it on mobiles. why not spend that time concentrating on the most important mobile export and stability.
The way I see it is like this:
-should a start a game for mobile? not is to much trouble yet, especially for none experienced programers.
-Then now comes the question, is it worth the feature to develop on tablets, phones, etc. for me...?
no yet because I didn't and I can't start any project for mobiles because is so much trouble still to release them on mobiles platforms. do you see were I'm going? so if there is no game to work in, doesn't matter how many cool features the software will have, will be not benefiting in any way until the bigger problem is address it.
