Authorize or not the reading of some branches
When I share large maps. I would have liked for some branches, that this one must be prohibit reading them to people who don't have the password. Inside a card this function is not possible, too bad. My current solution is to cut the card in half and put a password to open the new one, but that requires a lot of mental gymnastics.
IIt should be possible to set up a function that opens or closes reading some branches with a password (the same for a card and several different branches of course)
