Our editor integration is completely editor agnostic. Deno implements the Language Server Protocol [1], which essentially all editors support. Because of this the new inlay hints feature, is supported on all editors that support inlay hints and use our LSP integration. The Jetbrains integration for Deno uses our LSP, but I don't know if they support inlay hints yet.
You can find docs on using Deno LSP with other editors here: https://deno.land/manual/getting_started/setup_your_environm...
