Tenant selector for when one account has company admin privileges in multiple tenants.
A tenant selection drop-down similar to the one what is available in AzureAD. It would be nice to be able to navigate within the context of a specific tenant inside the O365 admin portal; this could be expanded to the entire portal.
I have a synchronized corporate account that I have added to multiple other tenants that I manage and granted company admin privileges in each tenant. This works great within the context of the Azure portal as I can select which tenant I would like to work in. It would be nice if this feature could be applied to the O365 portal as well. That way a person can easily switch between O365 admin portals without having to manage multiple accounts and without having to know the unique URL for each service admin portal for each tenant (Note: I think this only works with SPO). If there is no unique URL, it is not possible to access another tenant's service admin portal; this includes the O365 admin portal.
When managing multiple tenants, this would reduce the number of cloud identities required and password entries

This use-case scenario seems to be seriously growing, with the popularization of cloud services IT service providers can offer better easy to deploy solutions to their customers, in the other size service providers demands hassle-free tools
