How do I use "-extra" in VS Code

[jippi]

Hey,

I have a VS Code config file like this, and I would love for the "format on save" to apply the -extra gofumpt flag - but for the life of me, I can't make it apply in the editor. I tried looking through this repo and gopls, and nothing came up - so I'm assuming I'm either missing something really simple - or it's not something people generally do.

Thanks for an amazing project!

That's not possible right now, sorry. #251 tracks this :)
