There are a couple of optimisations I'd like to make to the account switcher to make it a little more useful.
- Only show account switcher in User menu if the user has access to more than one account.
- Display the "role" next to each account in the account switcher - currently either "Owner" or "Collaborator".
- Add optgroup titled "Switch to...", containing the accounts.
- Add a "View all Accounts" option which goes to /user/collaborations.
- Add a "Create New account" option which goes to /accounts/new.
