There’s a simple thing called “Show Desktop.app” which does as the name suggests. I created a shortcut on the desktop in the far right corner with an invisible icon and Unicode whitespace name, so that now I have a “show desktop” button in the bottom right corner of my screen just like windows. Can’t live without it.
The built in gesture/hot corner thingy doesn’t work the same way. The built in method “shows your desktop” but doesn’t minimize all the open windows like Windows does.
