Zenhub is great Matt, good to hear it's beneficial to you :)

I'm going to recommend it to others here, with a caveat: I really wish it would not be so aggressively hijacking the Github UI.

Tabs and side panels move around because the JS on the page finishes executing, making the Github UI feel super sluggish. We also have a lot of projects which end up with the settings tab in a "More" dropdown, despite Boards and Reports being more easily accessible from keyboard shortcuts (and we don't even use Reports)...

All those features are great, but there's no option to turn them off at the UI level, or customize them in any way. Very annoying :(
