On a list of PRs, it would be really awesome to be able to switch between draft and ready for review PRs with a button or toggle, rather than having to add draft:false or draft:true to the search query.

ideas:

• toggle to include drafts or not
• exclusive buttons for draft and not draft (same pattern as open/closed)
• three-way selector allowing for only draft, both, or only ready PRs
