I respect the work of the community and I don’t want to gloss over the many improvements in 2.7, but I agree that the interface has become too scripted, superfluous, and a tad unconventional.
As a designer and developer I fall into the same trap all the time, so I am not throwing stones. It’s tempting to do so many things in life, because we can.
The customizations feel on some level like proof of concept parlor tricks which don’t always streamline tasks or keep me oriented. I was also surprised at some of the type choices, and the overall busyness and lack of strong identity in the icons.
