Hey there, huge fan of the site! Thanks for all the hard work you've put into the best Magic inventory tool on the internet 
I was wondering if it was possible to implement a method (or if there is one already to point it out) of viewing what cards from a set was missing from your inventory? Sort of like the big set list here but with my inventory data as an additional column. As someone who aims to collect full sets, something like this would be super helpful.
Thanks again!
