Describe the solution you'd like?

Allow users to configure custom language servers that are not supported out-of-the-box in app

To add more color to the product behavior I think we should be building towards:

• We should directly support a neovim-like (https://neovim.io/doc/user/lsp/) config in our settings file. This adds that server into our set of globally installed servers
• The user flow here would be:
  • User opens a file editor. If this is a language we does not support natively, we show a link to documentation on how to add custom lsp configs
  • User can define the path to binary, arguments, and file types for a custom lsp binary in their settings file
  • Now whenever they open a file of the same language type, in the footer we can support showing “enable server X for repo Y”
