Problem Definition

When reviewing pull requests, if the reviewer wants to move to the next unviewed file, they can check the file tree on the left and look for files whose names are in bold. This can be a bit slow and difficult with pull requests that have a large number of files, especially when many of the files have already been marked as Viewed.

Suggested Solution

The request is to provide an option / checkbox "Hide viewed", which will hide files that have been marked as Viewed from the pull request file tree, so the reviewer can focus and more easily navigate to the files that haven't been marked as Viewed yet.
