Two suggestions:
1) Sending the payments once the block is mature with a "normal" transaction (i.e normal fees). Those fees can be deducted on the next block, to not harm pool fees. Also, since on the next block there will be a little more space for transactions (since the 0 fee transaction for payments its already sent) there will be a slight increase in tx fees recollected so for the miners will also be about the same economic result, but earlier!
2) In the payments page, state witch payments are already sent for easier tracking.
1) Why pay when there is a option for FREE?
2) I am pretty sure Kano mentioned that was on the list of things to do, but it was really far down the list.
