Flexible Haskell - a new plugin for JetBrains IDEs

This looks really promising! While I know it’s not the main responsibility of this plugin, I’m wondering how it plays with Nix/Direnv. I have basically all my Haskell projects as a nix devShell, and traditionally the Jetbrains IDEs don’t interact nicely with this. Is this something you think would be possible to improve upon?
