/confirm works this way
/confirm msg yes_cmd no_cmd.
this makes it pop up (for me) in top left corner of the window (x=0, y=0)...
maybe a "/confirm x y msg yes_cmd no_cmd" could be good. or just fixing the x and y values so it pops up at the same place than server crashes messages.
we also need a /nop (or /nothing) command when there is nothing to do for the no_cmd.
and something like a /shortcut shortcut_number should be cool to execute a shortcut (which can be a group of commands)
or something like /confirm msg (yes_cmd_1 yes_cmd2 yes_cmd3) (no_cmd1 ...)
concerning /buy and /sell,
will it be possible to do something like :
/sell harnquist 1 short sword
so ?
