Custom KOTH squares

The mods usually ignore the thread you posted a link to.
This suggestion was repeated multiple times.
That's why I posted a separate thread for it.

Indeed, right now we have to solve the connection problems, and improve some other general things. Next feature after things are more stable will be crazyhouse / setup chess/ pieces bank / drop support. I don't think we'll get to adding new rules like this until maybe towards the end of the year. But there are many good ideas, and we do take note, and have a long list of things we'd like to add some day.

Speaking of connection, it is very lousy. I'm on a VPN since Discord doesn't work in China.
And the connectivity is just as bad as the other players.
There should be an option that allows you to customize the squares for KOTH, so we are no longer limited to the 4 central squares.
