Hey Sergey,
Scheduler looks pretty good indeed.
But what's also missing in my opinion is a tenant structure.
E.g. Different email servers (+auth) can be configured for different tenants.
Wouldn't make any sense to only have 1 mail server, in a centralized video platform deployment, where different customers (so different tenants) are provisioned. Which mail server should be used then? Mail Server A to route all invites, also from all other customers? I think, we agree here, that doesn't make any sense.
Maybe it's a future feature addition.
