Very difficult to review large PRs with GitHub

[chriskuech]

Problems:

• It is very hard to review large PRs, so I would like to add more controls to make this more manageable.
• It is very hard to track open conversations in large PRs. The weird mix of content in the Conversations view is very confusing and makes all the content unhelpful.

Proposed features:

• A toggle for expanding all or contracting all files
• A file tree view like Azure DevOps shows.
• Adding an indicator at the top of a file showing that the file has an unresolved conversation in it. It is currently very difficult to track unresolved conversations.
• Add file filter for unresolved conversations.
• Have a separate "Timeline" versus "Conversations" view. Currently, the "Conversations" view is really a "Timeline" view and overloaded with non-conversation-related information, making the entire view overloaded and unusable. It pushes useful info (PR checks) way out of view in favor of unuseful information (every commit ever in that PR).

Any updates on this? This is making my job intolerable.

For anyone suffering with this I do have some JS scripts you can save as bookmarks. This is the only way GitHub is even mildly usable for non-trivial code reviews.

Check "Viewed" on all:
javascript:boxes=document.getElementsByClassName("js-reviewed-checkbox");for(let e=0;e<boxes.length;e++){const t=boxes[e]; if (!t.checked) t.click();}

Uncheck "Viewed" on all:
javascript:boxes=document.getElementsByClassName("js-reviewed-checkbox");for(let e=0;e<boxes.length;e++){const t=boxes[e]; if (t.checked) t.click();}

Load all diffs
javascript:boxes=document.getElementsByClassName("load-diff-button"),counter=0;for(let e=0;e<boxes.length;e++){const t=boxes[e];t.click(),counter++};

Load the next 100 diff (because why wouldn't loading 500 cause more performance problems?)
javascript:boxes=document.getElementsByClassName("load-diff-button"),counter=0;for(let e=0;e<boxes.length && e<100;e++){const t=boxes[e];t.click(),counter++};

Hope someone finds this helpful

Still in preview :(

Usually I refer to requesting the PR be broken up, but we often review the code changes made by linting tools in one swoop. Honestly, I don't mind the current PR format, but holy hell is the website performance slow.
