Questions about mods are best asked in their respective threads because then the mod creators will find them and get notified about them. Especially if you are talking about expansion requests for the mod, where nobody but their creator can help.
That being said, there is a gallery now in game (once you completed the game by marring a girl once and getting NG+), and it is doubtful that "setting to 100%" would be possible, since many progress events could be blocked by that. Also, you would miss most of the content, since the majority of stuff happens "along the way".
