Custom tags in Manage Cards

[merryaugust]

I would like the ability to add a custom tag to player cards in the Manage Cards screens. These tags would be available as filters. My primary uses would be:


-- To better view and organize tournament rosters without using a 3rd party tool

-- To protect cards used in tournaments from accidental sale
-- To organize cards for other purposes not covered by existing filters, e.g. market speculation


Creating filterable, custom tags would resolve these issues, and allow me to manage tournament rosters from outside the tournament itself. Thank you!
