I think its kind of sad we have to put 'a functioning award calendar' on the wishlist for the program, but that would probably be my top one.
I would like to see them add to the fare classes that can be used for SWUs, even if it meant PMs only could get 2 and DMs 4 (for example).
Upgrades on Amex companion tickets would be nice too. I'm fine with them being behind revenue tickets (or following normal companion rules), but my wife and I flew in Y this year using one when there were plenty of empty seats in F. Spare me the "if you want it, buy it," its just my opinion that if there are empty first class seats on the plane, a PM should be able to be upgraded.
