I enjoy playing and learning Go on OGS a lot. There is just a technicality that bothers me at times.
I sometimes get games that start without any direct action by myself. I know they stem from tournaments or the ladders, but nothing on the game screen tells me what the context of the game is. And even if on one day I know, I might have forgotten on the next day.
It would be nice to see that somewhere prominently. Like maybe above the boxes that count the time of the two players? Something like “Tournament X game Y” or “Ladder Challenge” and some indication of who challenged whom.
