I cannot overstate the VITAL importance, and invaluable usefulness of THIS very powerful extension. Esp.when used with Umatrix. !!HOWEVER; it MUST be STRESSED to the MAX: The USER become THOROUGHLY versed, and FULLY familiarized with ALL the settings, and details about what EACH, and every one of them does and or doesn't do.
To truly benefit, and get the MOST out of this top notch extension, becoming a well versed, advanced user is an absolute must. Links to all that info is included on the app. ~ This may take a few hours or days of study, depending on the user, but it will be well worth it, for beginners 2 advanced "You-zers." & 4 both UBO & Umatrix.
During the course, You'll learn a lot more than just how to configure the extension.
Not knowing these extensions inside out, is like owning a Porsche without knowing how to drive.
