For the Inbox section filter, is there a way to filter PRs by whether they have open comments?

(If applicable) To help us more clearly understand what you're trying to do, please provide additional details about: - Screenshots / debug logs / list of commands you've tried to run so far - Your workflow - Current state

like any comments filters?

Not currently, but a few folks have asked for this. I'll add ya to our feedback tracker so the team has more signal.
