Sent in the update earlier today for Compositions for iOS. I posted the notes earlier so you can read through them.
There are probably a few bugs and quirks in it, so I'll be publishing some follow-up updates to it quickly. I really just wanted to get it out there for iOS 7 and 8 though, because in my testing it all seems pretty stable and working. I think people will like the new icon, and the updated modern look. Pretty much all the functionality remained the same, which I think is a good thing. Why add complexity to something that works well?
I started working on a quick update for Compositions for Mac as well--to match the new icon, and probably update a few minor things.
