I just released an update to the gameplanning interface in MFN-1 for the play selection (offensive plays, defensive plays, scout offense, scout defense). You can now select the number of games back to scout, filter the list by the number of times the play was used, and choose whether to sort by number of times called, average per play, or your team's familiarity. You can scout your own team by looking at your own offensive plays as well, as the same information and filters are displayed there.
Let me know if you have any issues, if everything seems to be working well after a week or so I'll roll this into the general release.
