Start multiple sessions at once

[joshmedeski]

What would you like sesh to do?

As a user, I want to create a configuration that can start multiple sessions at once, so I can scaffold my workload by loading multiple sessions at the same time.

Example

When working in a monorepo, I want to launch a project/web, project/server and project/packages/core sessions all at the same time, since I know that's what's needed to start development.
