I love the Group and Quests features but it would be cool if when adding figures we could add "optional/Honorable mention" figures as a second category within each quest (you can call them side quests or bonus objectives for quests). For example with the fantastic 4 you could add She-Hulk and H.E.R.B.I.E. Or for a team you could have a character the crossed over with at one point for an arc in the comics. Or in the case of G.I. Joe you could have the toy "ninja force" Characters but can also have the characters that were part of or adjacent "Ninja Force" in the comics. Characters that are not necessary for technical completion but you can add them to the list just so that they are visible.

The other thing that would be cool is if I could save a quest as a group and vice versa. Maybe also have a picture option for a thumbnail and another for a background picture when you open the quest/group.
