Always show all the fare buckets for 'expert mode' on united.com.
Here in May 2019, this extension didn't do anything at all. Not surprising really, it hasn't been updated in 2 and a half years and united.com looks completely different today.
It's great. Use it all the time.
Should have rated this when I first started using a couple of years ago. Incredibly useful for travel planning!
