New UI section navigation much harder
The new UI is much harder to navigate than the old one.
I keep spending ages looking for a navigation menu option, then realising that I'm in the wrong submenu view and have to go back to the overview.
At the very least, the 'back to overview' button should be the same colour and style as the nav button you used to get into that view -- at the moment it's almost invisible.
It needs to be made much clearer which section you're in, and how to move between different sections. You could have symbols for each section in a horizontal line and make it clear which is currently selected. At the moment the UI is really confusing and inconsistent.
