Maintainers: what's one GitHub feature you wish existed for reviewing community PRs?

I've been maintaining an open-source project that's grown to a 170+ GitHub stars with dozens of contributors, and I've realised that reviewing pull requests has become the most time-consuming part of the project.

GitHub's review tools are solid, but there are still things I find myself doing manually over and over, like:

• Checking whether a PR follows the issue requirements.
• Verifying that it doesn't duplicate another open PR.
• Looking for architectural inconsistencies rather than just code quality.
• Deciding whether a change belongs in the current release or should wait for the next one.
• Giving similar review feedback to different contributors.

I'm curious how other maintainers handle this as their projects grow.

Do you have a review workflow, GitHub Action, bot, or third-party tool that has noticeably reduced your review time?

Or is there a GitHub feature you wish existed that would make reviewing community contributions much easier?

I'd love to hear how other maintainers have streamlined their review process without making contributors feel discouraged.
