Hi, many editor allow to show the signature and docstring next to each suggested completion item. See for example this screenshot where python-lsp-server and neovim are used:

If ty is used, no documentation is shown:

I suppose that for this documentation has to be returned with each CompletionItem, see https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#completionItem. It would be nice if this was also supported by ty.
