Here are my thoughts:

For the reviewers like Junio, after missing a new patch iteration, need to
review the past history to find the correct patch and related comments
from other reviewers. Just like I once read a github blog saying that
"patch" is also a special object in git. I would like to have a "new" tool
 which can link multiple related patches and comments.

1. Coder need Reviewers' help.
2. This new tool will obtained multiple different patches contents automatically
or coder provided those pathes versions links.
3. This tool will analyze the differences between multiple patches
versions, get all
the reviewers comments and coder comments related to the "patch stream",
organize it into "patch graph".
4. The tool will notify the reviewer(by email or something else) and
show the links
and patch graph or patch range-diff. It can visualize the entire patch process,
 It’s best that comments from different people can be displayed on one page.

In order to be more accurate, I made a picture [*1*].

Using this new tool, reviewers can choose to see or not see the range-diff
and diff in multiple different patch versions, Instead of the range-diff
automatically sent by GGG. When my second patch processing was greatly
changed from the previous one, I have to rebuild a new branch and create a new
PR, this is my pain point.
