If Construct 3 works for you and you think it's the best, just use it. There is no point in worrying about popularity of the tool. It sure is working for us over here at Scirra!
As for missing/requested features, what can I say? We work on the tool day in and day out :P
Having said that, it is ok to ask for more and better things, but at one point you need to work with what you got to get things done.
