I feel it would be really useful to be able to list all the cards which a given character can take which use a given loadout of talents as cross-slot management becomes more important, though I expect not high priority. Also, I feel like it would be more helpful for talent or maybe level to be the default sort in your own inventory as opposed to in shop; it would just make things a little bit smoother.
I'm not sure what you mean. Some sort of combinatoric deal? Currently, after all, if you have one clear talent then you COULD take any item with a one-clear-talent requirement. Or are you referring to having a "subset" button, such that you could display all "one-clear-talent items" (or whatever you'd like) and hide the rest? If so, sure, you'll find a lot of support for that idea on the forums.
Yeah, that's exactly what I mean! Except expressed better. I didn't know whether this was something that'd come up already.
