I am an Art Direector and UI designer by profession and I have to say that my eyes bleed every time I see a standard margin missing or UI widgets misaligned. Oh and 'square' rounded corners in the popup menu of the browser - like Chinese water torture And the sudden change in UI/UX when getting into 'advanced' settings pretty much anywhere. It's like having a sports car that's been built by hand and first someone lost the ruler and then the blueprints got mysteriously burned. The car still runs OK but the doors don't close properly and the fenders are borrowed from model a few years back.

Edit -> At least it's fast
