Out of the box, the “minimize on click” feature is disabled in Ubuntu. This can be quite annoying for people who are used to this feature. Even if you’ve never heard of this feature before you’ll find it can help speed up your productivity quite a bit.
For those not sure what this feature is. It enables you to quickly minimize an open window by clicking on its icon in the Unity launcher. Like you would if you wanted to show the window.
Here are two ways you can enable “minimize on click”. The first with Unity Tweak Tool and the second using the terminal.
