Oh come on.
Not only do they listen, they take the time and trouble to comment on almost every thread here. When have you ever known the Apple development Team to do that?
Marc’s post nails it but I’d like to add one thing, While Daniel and the team are very open in this forum, it’s all too easy to forget that there’s a competitive market out there for notation software. Showing your competitors your hand by publishing a list of future features isn’t the smartest move and, worse still, it will build up expectations among users to the point where dealing with those expectations becomes an issue and takes valuable time away from development.
Have faith. What they’ve done so far is excellent and there’s a lot more to come.
