This would be extremely helpful. I love using lock to make sure workshop participants (who are often unfamiliar with Miro) don’t accidentally move elements of the board around they aren't supposed to. But afterwards I want to be able to copy things (like entire frames) to a new board for synthesis, and unlocking each individual item is a huge pain.
I’m working on duplicating a board as a basis of a new board and want to delete some (but not all) of the old content and literally have to now unlock hundreds of items individually….
