Here is the list in points what I would like to see in the future DCS modules:
Most wanted:
Possibility to manage server using client,
Login using nickname and password,
Kick player from game,
Ban player: IP ban, range ban, UCID ban, nick ban,
Load and restart mission.
Additional features which can be used by authenticated client:
Possibility to change mission settings,
Time change,
Restarting mission using timer,
Show clients packet loss in percents,
Possibility to manage permissions for admins.
Also I'd like to have possibility to configure (enabled/disabled feature) something like this: if client connection will fail his aircraft will take AI. If he will come back he can jump in his plane. A lot of time saved while flying long missions.
Thats all for now :)
