[Feature Request] Show percentage of how far the entire diff has been read

[inamiy]

Hi, thank you for creating this amazing tool 👍

I'm not sure if the feature already exists or not, but I would like to have a new indicator that shows "how far you've read the diff" (in percentage or line of code, e.g. 1234/5000).

This indicator will be very helpful especially when I code-review someone's gigantic pull request locally and figure out how big the changes are and how far I've read, so that for example, I can pause the review at some percentage and come back later a bit more easily.
