CREATE FUNCTION
CREATE VIEW
As yes, I am being mostly serious - though I have been pondering seeing what tools can do as opposed to the manual formatting I've been performing. Even a basic linter would be helpful...
The big problem is you need to define what it means to be beautiful. Understandable is a totally different area and that is more where views and functions come in so you can provide names to the various constructs you are using. CTE/WITH facilitate this as well.
