I use it constantly in helix too. The vscode one is meh. I think I saw a discussion in github once about switching to tree-sitter, which would improve AST-related actions. I don't think it went anywhere though.

I love AST aware editing. I think it's one reason it's always been so nice to edit lisps. Stuff that is complicated to describe in javascript (and doesn't have LSP support) p much requires a whole AST parser, but in lisp it's just a simple list operation. When I go back typescript after a weekend of clojure, I reeaally miss slurp! and other paredit commands
