This is a serious question, I'm not being sarcastic or digging (this time :))
I've searched and even purchased some Notation apps, not for composition but for sharing with other players and to document ideas. It's really easy to revisit things with an acoustic guitar and printed chart without having to be tethered to a PC.
Anyway, in my searching I've noticed that the major players all support score playback via VSTs. So if your thing is composition, wouldn't it make more sense to use a purpose built notation application? They provide playback for that is at least good enough for writing.
Then when a score is finished, move it to a sequencer for the more powerful samplers, softsynths and mixing capabilities?
Or are you folks really in between these extremes, looking mainly for fixes?
I've visit enough scoring application forums to see that even the most sophisticated notation software has a never-ending list of requests from users. So I wonder if Cakewalk went down the Staff View path, at what point would folks be more/less happy with it? Or would it end up being perpetually inadequate until Staff View capabilities rival those of the top tier scoring tools?
Seriously - I'm not making suggestions or trolling. I'm just mulling this over trying to look at it from the developer's perspective.
I'm guessing here, but I doubt Cakewalk is a cash cow for Gibson right now. I'm betting they have a ton to do in all parts of Sonar and their other products trying to build the income stream.
