GitHub PR Quick Filters од Tyler Day

GitHub PR Quick Filters adds a "Quick filters" dropdown to any repository's Pull Requests page, so you can apply your common search queries — no drafts, ready for review, your own PRs — with one click instead of retyping them or hunting for bookmarks.
Each filter has a label, a GitHub search query (any string you'd normally type into the PR search box, like is:pr is:open draft:false review-requested:@me), and an optional author field that's appended automatically. Build them once in the toolbar popup, reorder them however you like, and they'll appear in the dropdown on every repo you visit.
Mark one filter as your default and bare visits to owner/repo/pulls will redirect to that filter's URL — so the moment you land on a repo's PR tab, you're already looking at the slice you care about. Switch to a different filter at any time from the dropdown. Filters sync across browsers via Firefox Sync, so the same set follows you between machines. There's no account, no server, no telemetry — the extension only reads the page you're already on and stores your filters locally in browser storage.
