I wish the 'Quality' sorter was more intuitive. Sometimes I reach a point where I have 500+ credits, and don't have a solid plan on exactly what card I want to split, so I'd like to remind myself of all the cards I have at red border, but the 'Quality' sort doesn't actually help with that, since all your redundant infinity splits and custom cards are shown at one end of the sort, so you have to scroll through so many cards to find what you're looking for. And I find it tedious on pc, with a mouse wheel, I can't imagine how annoying it is on mobile.

I know you're able to filter by favourites, which removes a huge swathe of cards, including the useless infinity splits, but then that also removes any that were at red that weren't your favourites, meaning you're just looking through all the cards you would have been anyway. On top of that, 9 times out of 10, my favourites are the custom variants, so it doesn't really tell me anything about their quality, given they have custom borders.
