There aren't many (if any) "medium to bigger" FR's they haven't already been heard or made months ago. There are always some small things the exist somewhere that slip under the radar
of people who may not use a certain product, or FR's that come out of current behaviors that wouldn't have come up otherwise but all of the usual stuff has been FR'ed for S1 since day one... if not before release day by it's beta testers or others with access.
Also, a good portion (if not all or most) of the people on the team are musicians/users who've obviously used other daws so they're probably making a lot of the same FR's that we are.
I think their "todo" list is pretty long.
It does get wacky at times, some of the demands for FR's that maybe cannot be highly prioritized early on in a relatively new product like professional scoring, when there is so much more basic stuff left to do. I think they'll eventually get to most of the important stuff and along the way do some cool things that nobody has really thought of or asked for, like the automation transformer.
So personally I hope they find a way to get some of the more important editing stuff (and those kinds of things) done, but do it in their own way and not try to copy the others too much. One of the reasons I like it is because it's not like the others... so far. Lots of ways to skin a cat... we can't assume that all of the current ways are last word in the best ways. They only are until you see a better way somewhere else.
I think they made that point (at least partially) already with the general UI... so hopefully that trend will continue.
