It should also be borne in mind that not all features are equal in terms of effort and resources. Some features may require many more man-hours than others. (And if I had a pound for every time someone said “I’m sure it would be easy to implement…”… 
)
If the most popular request is also the most difficult, do you throw all your resources at that one problem for six months, doing nothing else, or do you get lots of smaller things done while putting aside some effort for the big problem, slowly?
I, for one, could not wish for better project management than I have seen at Dorico these past couple of years; and I’m more than happy to just let them get on with it. If your pet feature isn’t there yet: wait a bit. It’ll come.
