Secondly, this topic is in no way intended to be a slur. C2 is a fantastic tool and both Ashley and Tom deserve well earned praise - these guys are doing an awesome job!
Thirdly, I think it would be true to say that most people using C2 view it as a real-world production tool - not simply as a toy, and rightly so - it is not uncommon to see Construct 2 referred to as Ground Breaking on the web.
So on with it then:
Now to be sure everyone likes to see new features added - it really is very cool!
But it is also very important to fix known bugs first - or at least I think it is.
If you visit the bugs section of this forum you will notice that certain bugs have been unresolved - even after many updates have been released, in fact some of them have been unresolved since I started using C2 (version r114) - some are minor some are not so minor - but they are all BUGS.
It doesn't matter if a bug is minor, major, or in between, a bug is a bug and should be resolved as quickly as possible and certainly before any stable release is posted.
Now I know Scirra is just a small team - but this tool is no small puppy - so it is only reasonable to be patient for new features. I really think that most C2 users would prefer bug-fixes over feature additions.
What I would like to see:
1) Stop adding features - just for a while
2) Iron out the bugs
3) Release 'Stable' update - with no known bugs
4) Add next awesome feature
5) Release Beta - expect bugs to crop up
6) Start at step 1 again...
