Add more customization to live folders

[TrevorCollins]

I love the live folder for GitHub Pull Requests, but I wish I could configure it a little more.

My team loves to use draft PRs for personal development and review before sending to the team for review. It would be great if I could filter these out.

We also have an issue with opening PRs and never closing them when the work is abandoned. So some of the repos I'm connected to are bloated with old PRs that are way out-of-date. It would be great to be able to filter out by days since last commit.

Basically, all of the GitHub search filters would be very useful

Thanks for submitting an idea to the Mozilla Connect community! Your idea is now open to votes (aka kudos) and comments.

I know that was a feature of the Arc browser, but pretty sure Firefox hasn't got an equivalent, unless it's a new feature in development, or an add-on perhaps?
