Ability to tweak the shadow depth of windows/menus

Provide the ability to tweak the depth of shadows on the menus and open windows.
Option can be provided as one of item in the System Settings.
Example of customization is at least like the one in Cinnamon css , eg. box-shadow: 0px 5px 20px 12px rgba(0,0,0,0.8) but provided in user friendly interface.
Also provide the ability to save as part of theme.
Changing the window's shadow depth definitely will improve further the look and feel of Linux Mint UI (example like the one seen in Elementary OS)
