User Problem

Unable to unarchive multiple cards at once or delete them.

Suggested Solutions

It'd be great to have the option to select all cards in the archived section (give you the ability to unselect a few if you want) and then bulk unarchive or permanently delete the cards.

Current Workarounds

If you want to delete all archived you can copy the board and then delete the original board, copy a board doesn't copy the archived cards to the new board. 

Deleting a board is permanent and can't be restored, you'll lose everything inside it. 

Unfortunately, at the moment, the only way to unarchive in bulk is to create a script and use API to achieve this goal.
