This is great for what it does, but I want a more generic LLM integration that can do this and everything else LLMs do.

For example, one key stroke could be "complete this code", but other keystrokes could be:

- send current buffer to LLM as-is

- send region to LLM

- send region to LLM, and replace with result

I guess there are a few orthogonal features. Getting input into LLM various ways (region, buffer, file, inline prompt), and then outputting the result various ways (append at point, overwrite region, put in new buffer, etc). And then you can build on top of it various automatic system prompts like code completion, prose, etc.
