Add minimize button to windows
One tiny issue you’ll notice is the lack of a minimize button on windows. If you’re like me, you depend upon that button quite a lot. Now that you have Elementary Tweaks installed, getting that button back is as simple as:
Click on Appearance
Click the Window Controls drop-down
Select the option that best suits your needs (I opt for Minimize Left to mimic the Ubuntu Unity window control—Figure 5).
At this point, Elementary OS Freya should be tweaked to perfectly meet your needs. If not, there are still plenty of customizations you can manage from within the standard Settings tool and a vast amount of software to install to help you get the job done.
