What's holding up the ability to change models?

What's holding up the ability to change models?

#235 should be merged first.

And it has a blocker sublimehq/sublime_text#6424 (not sure whether we can workaround this in ST)

[TerminalFi]

@phene Yes, as @jfcherng stated, while functionality wise this works. When we switch over to the GH provided npm package it is 200+ MB and that causes ST to fail loading the files sadly. There is technically a potential work around, and that is to change how LSP looks for these files :) But I doubt they want to diverge from the build in solution.

The other option is that we can put these new commands behind a setting, and tell the user they must provide the package and update the settings.

I highly encourage you to contribute. It would be greatly appreciated

I have update to the latest server with npm install --lockfile-version=2, which is compatible with yarn v1.
