For people who like to review their decisions more than once, saving them as positions provides several advantages over saving them as matches or sessions.  Unfortunately positions are a little awkward to retrieve (see my enhancement request 32570) and I think this must discourage people from using saved positions.

A solution is to enhance the "Next/Previous Marked Move" function with up to three new toggle switches:

1)  Comment/Error - When originally viewing a match or session, the default action of "error" would be used.  After adding comments and saving the file, it could then be reviewed by toggling to "comment" so that only commented decisions are displayed when "Next/Previous Marked" is used.

2)  Normal/Full Screen - This option results in entering full screen mode each time "Next/Previous Marked" is used.  This is useful to hide results and looks pretty cool too.

3)  Normal/Player on Bottom - This flips the board so that you can view the decision from your usual perspective.

The toggles would all be evaluated independently of each other and naturally the last two could also be used with the other "Go" options (Cmark, Move, Game).
