On Trello, hide/display all of the cards of which you are not a member!
When using Trello in a team, it can be annoying looking for the cards that you are members of. With this extension, you can now filter out all off the cards of which you are not member with a single click! And the second will restore everything.
It also automatically hide all columns with no visible cards.
All it does is hide them, so nothing is change on your board.
