Life In 19x19

Sensible ( basic, fair, natural ) features on a ( crowd-funded? 9-year-old ) 2019 server ( Lichess.org ):If a user has a habit of sitting out the clock ( loss by time ) when behind instead of loss by resign, the server issues a warning of a ( temporary ) ban.Afaik, kgs is the only server that penalizes a user when their opponent leaves a game ( involuntary or voluntary disconnect; or escape ) with an incomplete game that doesn't indicate who first left. No other chess, shogi, or Go server does this, afaik. imo, this is one of the most ridiculous "features" ( by design ) of kgs.

The first two features are not that easy to implement, especially the second one.

KGS auto-forfeit for Rage-Quit-Escapers seems reasonably close to the Temporary ban for always losing by letting the clock run out.
To be honest, I'd prefer UI and client updates instead.

seems reasonably close

No.

UI and client updates

shin.gokgs already has many UI improvements, but for whatever reasons its development stopped.
