So maybe this exists and i just can't find:
I have two PCB in one project, but unlike with couple schematics i don't see a way of opening two at once.
It would be nice to manage them the same way as schematics with this small bar:

Or just option to open other PCB from project in the same editor, as there is a way of making and managing couple of PCB at once but i don't see a way to open two at once, even clicking Open in editor on whole project open just one
