This is awesome, I hope I get a chance to use it once.

One thought: I think the effort should be put into the UI for the non-technical end users, instead of query builders/developer experience. I would be even fine with a tool doesn't even have a query tool and just executes SQL files from a folder/git repo. The important part would be for me to provide a perfect experience for the end users. Developers usually have a lot of tools at hand to create queries, no need for another one.
