Came to think of a feature that would be very nice to have:
Say you are planing some major new features to your app and thus make a new major version. While you are doing this you have to fix bugs in your older version that the users still use.
So, it would be very handy to be able to "push" these minor changes to the new major version so you don´t have to make them in two places!
Don´t know if this is doable but it would be a very nice feature!
(I take for granted that every version today live completely separate lifes, correct me if I´m wrong..).
