# Implement multi
# test headers->clients
# Still use single client in subs, but have it only be set if a single on is selected
X Pass X-Clients header as :all :mine [id-1, id-2, id-3]
X Use X-Clients instead of client filter
# Remove the client specific filter from each graphql
# Test with single client user, all client user, admin, etc
# Synchronize with the backend for SSR, set in session, but hydrate to real clients in middleware
# Ensure that client selection still resets everything
# maybe set it up so that changing assignments works automatically without having to log out or in
# figure out how to not make this require a whole login
