Thanks for the link. Unfortunately it seems it is currently removed due to unclear bugs.
Damn, you're right, I didn't notice the notice, nor am I a daily Calva user.
But so what, is there no automatic balancing of parenthesis in Calva? That seems to diminish the value from the extension by a lot, I couldn't imagine coding Clojure and having to manually balance parenthesis.
You have this basically already. When you move forms in/out on the indentation levels, notice how the brackets/parenthesis automatically re-arrange themselves? That means it's working :) https://calva.io/parinfer/
