Interactive item housing permissions.
I would first and foremost like to have interactive objects modified through a housing menu, as this would solve the issue we just had as the person would have received an error trying to make modifications. If not that, we absolutely need some kind of permission lock down on interactive item access. Someone just came through our fc as a lvl 1 with no permissions other than entering the house and removed all the flowers from vases and all the pictures from picture frames. It's not a big loss (had the chest locked down luckily, I'm sure that would have been emptied as well otherwise), but it's an issue that needs to be dealt with.
Edit: Just to clarify and not cause extra worry, this still requires the person to have fc/tenant access to the house. Just having guest access so anyone off the street can come in and view the house will not allow them to mess with your interactives.
