I would like to see the following options to streamline PBEM play:
(1) Autopass until the end of the round
(2) Autopass until a share is sold
(3) Autopass until something interesting happens (share is sold or company floats, for example. For some games, a company selling out might also be of significant interest -- for example, in 1835 one company selling out might make the director's share of another available. I believe that the class of "interesting events" could be global, not game-specific, without giving up much optimization of PBEM experience.)
Autopass until the end has been implemented.
After an autopass, a player can now ask another (still active) player to enter a Turn Request on his/her behalf. The autopass will then be cancelled.
Other autopass options may be considered later.
It would be nice if I could indicate autopass as I make my last purchase on a round, rather than needing to wait until my following turn in a stock round to both issue my first pass and autopass.
For example, if on a stock round I plan to buy 2 shares then autopass, currently, this takes three turns - buy share + buy share + autopass. I would like to instead use only two turns - buy share + buy share & autopass
