Sort list of tenants in alphabetical order (by default)

For admins who are active in many tenants, the list is long and not sorted. Having it sort in alphabetical order would make the list more clear and easier to find a certain tenant. This would be the easiest improvement to implement, I think. Another idea is to be able to make certain tenants "invisible" in the "Personal settings" page, so it would not show in the quick list. Ofcourse users should be able to undo this too and make tenants visible again.
