I don't have the new design yet in any of my servers, but this sounds nearly identical to the iPad layout, which I've grown accustom to and don't mind.
This happens in every redesign. People push back and claw their way to use the old design, eventually it becomes completely inaccessible. Three years later and the same people will complain about the next redesign again.

Slacks done redesigns before that were well received because it didn’t affect its functionality in the workplace. This does.
