Short of a God's-gift-to-programming, Linus Torvalds type celebrity figure, I can't imagine any programmer retaining exclusive rights to a work product done for a company, under contract or otherwise. I think the problem is more one of dollars and cents; once the staff view was originally completed and worked well enough, the focus (and the userbase) shifted toward audio production and that's where the programming focus has stayed for years. And years.
And years.
At least until the PRV got some love the past couple months. Hats off to Cake for giving it some attention, for sure. But my guess is that as the staff view code has aged, it has become a bigger and bigger project to overhaul it, and with staff view diehards such as myself making up such a small percentage of the userbase (and thus income), priorities go where the money is. I don't fault Cakewalk for that, necessarily, as it makes good business sense and has obviously kept them afloat so far.
Doesn't make me want staff view fixes any less, though. :)
