Been using this site for a while, I still want to have additional filters available (sure, I could export my collection and use Excel, but i can't do that from my phone at my LGS when someone asks me a question).

* Filter on total number owned across all sets (still desparately need this)
* Filter on collector number of card (especially with all these variants, collector number is the only way i can differentiate some of them)
* Filter on artist (not as necessary as the above, but would be nice to have)

I know if you use the "Card Database" and put appropriate filters, you can get it to give you the total owned across all sets.

That being said, it would be helpful to have an option in the Inventory to do so. I was actually thinking to ask for this today, in addition to being able to search cards you own by language.

I also kind of wish there was an additional coloring on the set pages to indicate when you own 4+ of a card but don't have 4+ of in that particular set.
