• Plug-in system to allow for new game modes without the need of recompiling
Its marked with orange, means "Possible but uncertain future feature".
But I think a plug-in system could bring new possibilities to teeworlds and with it new players, for mods and vanilla, too.
It could be also managed for a more easy adaption of vanilla teeworlds. You wouldn't neither need to restart the server, nor to use several server applications.
Just drag the plug-ins to the server plug-ins folder, reload the server and its done.
This way you could take many little plug-ins and create your individual server...
For sure it needs some more protection to guarantee plug-ins using servers aren't shown up as vanilla game modes.
It could be done with some modification in the server browser.
The server would send an information, if a plug-in was detected, and the serverbrowser would show it.
