This is in the middle of a complete retool. We are currently working on a new database model and we are implementing dbatools into this module. I will review the PR's submitted after the Retooling has been completed.

Thank you for all of your updates as well!

Hey @js0505, this is my co-worker. We have been talking about the retooling and started to make some movement towards that. Should he submit this to the retool branch instead?

[jstexasdba]

Currently it is set to be merged to the ReTool branch once I review and approve.

I would hesitate on doing more changes as we are working on the new database model and I actually have submitted it to someone for a review process. Once the database model is done is when we can really go to town with updating and creating new PowerShell functions.
