Definitely a cool feature! I'm not particularly a frequent MTGO player, but I'd like seeing greating integration for them (like being able to tag decks as 'MTGO-metagame' focused, and/or being able to export decklists in a ready-to-import format for MTGO, thought I don't
recall if MTGO used some proprietary format for deck files)
Kudos for the frequent updates and constant effort!
