Azure tried to get fancy, with side sliding panels all over the place, and it is barely useable. The nicest thing I can say is it is "quirky." It isn't really productive however, particularly not on my 1080p monitor at Windows 10's default 125% DPI.
I literally quit Azure's Application Insights and went back to Google Analytics simply because I hated the Azure UI with a burning passion of a thousand suns.
The concept of writing queries is good, but if that's the only way you can get at your data you better make it damn easy, and they didn't. I'm sure for full time data pros it is a dream however.
Our Azure SA was giving us a presentation and actually got confused himself. "So that's TFS... I mean VSTS... Actually wait, it's Azure DevOps now?"
