CodeHerald
CodeHerald provides a new way to keep track of your code review queue, grouped by your next action needed.
If any of the above is true, CodeHerald will help you.
CodeHerald groups pull requests by next action: must review, needs an update, can be merged. It allows you to replace slack, emails, filters, and browser bookmarks with one single page that you can open at a glance and decide which PR to tackle next.
