I agree, the new version is super huge for me as well. I was kind of surprised when I went into appearance setting looking to make it smaller and only found options to make it even bigger… 
And “Compact Mode” doesn’t seem to really do anything at all. So there definitely needs to be some more options to manage that. My password manager extension shouldn’t cover half my browser screen.
EDIT: Okay, so it’s not “half my browser screen”, that’s an exaggeration. It’s still enormous though.
