I was poking the Microsoft store with a stick again to see what would fall out and look what tumbled out: Enhancer makes a number of changes in the way Youtube behaves, including volume control with a quick flick of the mouse wheel. It does other stuff too, but the ability to scroll the volume is exciting. Yea, yea, I really need to get out more, but seriously, it's great. Enhancer, by MRFDEV Web Development, offers a number of options, including blocking ads, disable autoplay, set automatic screen size, and much more. It's worth a trip to the store to check out, especially if you watch a lot of YouTube. I personally like the option to preset the video to start on a specific screen size and quality and disable autoplay.
The only teeny thing I have to complain about is accessing the controls. They are placed at the very bottom of the page (very unobtrusive) and occasionally a bit tricky to click. I have a couple customers who have control issues and wouldn't be able to tap that tiny control panel without a major hassle. It would be nice if the pop up was a little larger.
To download it for Edge browser, fire up the Store app and search for Enhancer. It also comes in Chrome, Firefox and Opera flavours so you get to choose which browser you prefer.
