I just came onto this forum to post that exact message, you best me to it by a day!
Totally agree, I always go "right I'll add some conditional moves here" and then get ushered into the next game, so maybe a little tick box that says "one I submit move go to next game" and you can untick it everytime you don't want to?
When the opponent is not online, I don't see the option to "stay on this game" after I move. This used to be logical, but with the addition of conditional moves, I find myself wanting to stay on the game when my opponent is offline so I can enter conditional moves.
