FWIW, the author of Doobie doesn't even use an IDE, which is par for the course I believe for users of Scalaz, Cats, Shapeless, etc. inference heavy libraries.

Abstraction isn't free in Scala, you pay for the features used; tooling suffers as a result, thus projects like Twitter's RSC come into being.

You may want to checkout Quill, or Perhaps Slick (though the latter I suspect is similarly IDE challenged). Barring that, give your IDE loads of RAM.
