It can be useful to see all open pull requests in all repositories that one owns, not only the ones which one authored (which is prominently documented on the search bar).
An example: I have activated automated security updates for dozens of repositories. Across my account there are now scores of PR's authored by dependabot. I wish to list all these very similar PR's so I can review and (mostly) approve them conveniently. I want non-dependabot authored PR's as well because I know in some cases maintainers volunteered to make the updates with close scrutiny. I prefer these PR's in most cases but still wish to review them.
