1. Keep a P Club in BOS
2. More standard reward/mileage upgrade availability
3. Gate standby for BF upgrades (the no-upgrades-within-24hours, we'll-fly-with-seats-empty rule is awful)
4. Introduce Y+ product on TATL/TransPac routes (especially since CO will be cramming 3-3-3 into the new 787s)

I'll disagree with Otter, the OP, on at least two items:
1. Keep us AMEX Platinums in the P Clubs
2. Have some real food in the P Clubs and if it means a small charge for booze in the clubs, so be it.
