1 and 2 are in the realm of bug fix / minor enhancement. 4 very much depends on where you are in terms of both how much deals cost and how they're structured and what that money means to you but in any case it's not killer. 3 is definitely the most interesting one though it still doesn't feel enough like magic to sway me just yet.
