Converting to draft and will let it marinate on my server, since some fixes introduced new bugs (fixed them, but there might be more)

Do you have any updates regarding this? Otherwise I'd cherry-pick some of these in the coming days.

So far haven't noticed anything else broken with the basic functionality of adding/removing friends, setting friend as read only or read/write.

Though setting a friend as a Manager is kinda broken, didn't test it much, but if a Manager opens Redstone settings menu and then closes the menu - all redstone settings become disabled

Probably best to cherry-pick yeah

EDIT: Oh oops, commented from my other GitHub account...awkward xD
