MacOS – How to hide Dock on non-fullscreen desktop

desktopdockfullscreenmacos

I want to hide Dock on non-full desktops. It takes a lot of space so some applications are hard to use in such small amount of space, but on the other hand I don't want to keep each single application on its own desktop, because of logical grouping.

So is there any way to hide dock and make program take extra space used by Dock. like on the full-screen desktop but keeping multiple applications.

I would be grateful for any help.
Thx.

You can hide/show the Dock by pressing optioncommandD which checks/un-checks the Automatically hide and show the Dock checkbox under System Preferences > Dock, and then application windows can occupy the space normally used by the Dock.

When hidden, you can have the Dock temporarily reappear by moving the mouse to the bottom of the screen (that's assuming you have it in its default location).
