Do you miss something on BrainKing.com and would you like to see it here? Post your request into this board! If there is a more specific board for the request, (i.e. game rule changes etc) then it should be posted and discussed on that specific board.
pgt: Auto-pass for backgammon (and related games) is perfectly fine as is; at a minimum it fits the rules of the game, which doesn't always happen in games on this site!
I realize that some players would like another auto-pass option, one where if you are on the bar but have the option to double, you can click a box somewhere and you can give up that doubling right until you choose to unclick the box (or something like that).
I personally would never use that option since I would be giving up equity. I would also stop playing gammon games here if such a rule change replaced the current auto-pass feature instead of becoming an additional option.
Fencer has stated repeatedly that he has much higher priorities in terms of making Bk a better site, and I think he is correct in that point of view.
By the way, I like the idea of being able to flag particular games, although as a pawn there is no point for me personally using it. For example, one could flag all tournament games that contain a long time control, thus making it easier to play those games when you don't have time to play every game each day, or each log-in session.
