Just want to say that I love the new sidebar navigation for the admin UI 
It takes a bit of time at first to re-train muscle memory… But then it’s such a nice flow to switch back and forth between forum and admin ui!
Also love how it de-clutters the previous navigation that had the two horizontal bars sandwiched on top of each other. I think it’s a great step towards a more modern and simple admin UI 
I will post it today. Glad you are liking this change so far!
