Currently it's quite a lot of work to onboard Atlas Clusters especially if you have a lot. We have 80+. It would be a great if there was an easier way to create Cluster connections within Compass, whether that be an export/import process or you just connect it to Atlas and it works it all out via an API.

To further support this it would also be great to set username/password details and preferences like secondary at root or group level so that clusters under root or group can inherit those credentials rather than filling in for each connection
