This is why I love macOS. Every application has the menubar at the top with everything in the right place. Apple's design guidelines also dictate that every action should be available as menu item. Preferences can always be summoned using the same keyboard shortcut, File open/save dialogs behave the same.
It just works. Except for those few applications that are plainly ported from Windows or Linux without a thought about the native platform they run on. They just don't fit in.
Then you want to disable mouse acceleration, and you're humped. Apple's approach to simplicity is just to extinguish user choice. That's not a great approach.
The trick to disabling mouse acceleration is not to move the slider all the way to the left. I believe it’s the position two notches to the right of the lowest setting which gives a linear response. Above and below that point you’re flipping the concavity of the curve.
