I also submitted my feed back.
Now you have to open left side menu to go to drive>folder>subfolder>subfolder.....etc.,
Before it was just one click, drag and drop to previous folder on Windows Exploder's address menu bar (intended no spelling error). Now I have to click to find the sub folder, then hope I won't drop the file to some disconnected network drive(which will free Windows for searching for disconnect folder) or different folder by mistake.
Very very annoying.
