Today I learned that since macOS High Sierra onwards you can move a window by clicking on any part of it (just like on Linux):
For some reason this behaviour is hidden behind a setting accessible only through CLI 🤷♂️
It can be enabled by running the following command:
defaults write -g NSWindowShouldDragOnGesture -bool true
And logging out of the current macOS session.
You can then cmd + ctrl + click on any part of a window to move it.
P.S.: To disable this behaviour, you can run:
defaults delete -g NSWindowShouldDragOnGesture
