It’s quite funny. 2012 I’ve used the first time macOS (or how it was called OSX) in version 10.6.8. Now Apple has reached 10.15 and there is still no proper, simple, menu-guided way to enable an file-explorer for productive use.
How to show the current path in the title of the finder:
(bash and then enter those two lines for configuration and restarting the Finder)
defaults write com.apple.finder _FXShowPosixPathInTitle -bool true
How to go to a known path:
Ctrl+Shift+G -> then enter the path.
