I know there are other threads out there for this, but I really think docker-compose yml support would be really nice. The Docker UI thing is nice and all, but I think creating an XML file for everything I want to add can add overhead.
Example: I want to use this inside Unraid, but it would be nice if it would also have UI support. https://github.com/hardware/mailserver
The way I'm thinking about it an addon to the current Docker app, where it can import/edit docker-compose files.
