1. Ah, this commit message feature isn't available in JetBrains yet, unfortunately. Most things carry over since they both use the same underlying code, but this is more editor-specific.

2. Your "reasonable near-term goal" is right in line with what we are thinking. Basically, "auto-edits" is f(edit that meets deterministic trigger criteria) --> multi-file diff. Here are some examples we have in mind; any others you had in mind?

update a type signature --> ripple that change across to all call sites/value literals (kinda like symbolic rename does today, but for more than just the name)

rename something --> update the docs

change code with a comment nearby --> update the comment if it's now invalid

update a func impl --> propose a new test case
