Enable minimize on click

Click on an app launcher icon to open an app. Click on the same icon again to minimise the app. Intuitive, right?

That may be, but it is not the default behaviour in Unity — which can be off-putting to new users. It’s also not obvious how to enable it.

Run the following command (or install/use Unity Tweak Tool > Unity > Launcher > Minimise):

gsettings set org.compiz.unityshell:/org/compiz/profiles/unity/plugins/unityshell/ launcher-minimize-window true
