while this topic is discussed:
I think basically all of them are only useful for a while, and then another one is better. I'm finding myself switching between them very often; so what I would really like is the setting:
'go to next game of this type, if none found go to game of similar type, if none found go to next game.'
that way I could go through my 150 moves without ever changing the setting, getting the games presented in a useful sequence, grouped by game type and game (first all Backgammon games, then all Nackgammon, etc.)

I understand that this is a bit more complex, but I could imagine that such a setting would be nice for a lot of people?
