If I login as admin and go into a customer's site, I cant switch to a different customer's site from the dropdown. It would be nice if this was possible and it would automatically switch to impersonating the owner of the newly selected site.
Obviously the list would be quite long on large hosts so perhaps a popup would be needed to support scrolling or search / autocomplete. Or allow tagging / favoriting sites/packages/customers and only those show up.
Would be useful if you have a number of sites with different owners that you frequently have to log into.
