Ideal shortcut for this would be similar to Slack – CMD + <NUMBER>

As well, "email" should technically be setup as a workspace (or organization) so that people can have external communication in a set place, and internal communication (for any workspace) in a separate place

There should also be the ability for people to move information (threads) from one organization to another

Just like with Slack and Notion, it'd be nice to be able to switch between workspaces and easily see which org I'm operating in now.
