When looking at the inventory (not managing or deckbuilding)
It'd be great to have the ability to:
1.) filter by set.
2.) filter by "legality" (i.e. standard, modern etc)
3.) have a cost column
I know these exist in the deck building area, and I am happy to just use that, it'd just be nice to be able to do that from the collection screen too without having to go into a new deck or go into manage mode.
Also, do you accept donations or anything like that? The amount of times I've been impressed/used this site... countless, keep up the great work!
