Really appreciate what this app offers, here are some suggestions I think would be convenient.
- Badges representing cart/manual/box that can be seen next to the right of a game title in list view. Theres plenty of room for them.
- When looking at individual games, swiping right to move to the next game on a list, allowing you to browse games at that level without hopping in and out of the list.
- Ability to estimate the value of any given list by cart/manual/box or all.
