Signature help

[matoous]

Another nice functionality that can be built on top of LSPs is signature help. Vim equivalent: https://github.com/ray-x/lsp_signature.nvim. While helpful it also clutters the UI quite a bit, especially when combined with autocomplete. Something worth considering?

Press space + k for docs of the thing the cursor is hovering over, and #417 adds virtual text. Not sure if that's exactly what you mean.

Kind off. Signature help shows just the types expected by given function instead of the whole documentation. Very similar but slightly different.
