I realize it's a bit of a hack, but do you see any practical drawbacks or issues in using tx_id fields for sorting transactions when their timestamp fields are equal? That seems to work well in addressing my UX concerns.
tx_id is not part of the protocol and should not be sent at all by the server.
it is a field that is only returned by abe-based servers, not servers using libbitcoin
D'oh! Story of my life.
It would really help if it were possible to recover those protocol docs (the link you posted on another thread is still down). What is libbitcoin? It seems like it might help to document the different kinds of servers, as well...
