Currently, I think the way that collections are presented to users is a bit unintuitive. The idea seems to be that what you click in the “All Vaults” section dynamically changes the section below it. However, this isn’t immediately apparent because “All items” implies that the things you are seeing below it are global in nature, not org-specific.
I think it would make more sense to have assigned collections nested directly under their org with a collapse/uncollapse toggle switch. Additionally, putting the name of the selected org in bold font at the top of that second “All items” section would do a lot to clarify that the favorites, logins, etc listed are specific to that selected org.
