What needs to be done to improve scrolling and zooming in Edge (Chromium)?

My laptop's touchpad is tiny which makes it unpractical to use for constant scrolling. For years I've been using the touch screen of my laptop to scroll/zoom and it was great on Microsoft Edge. Actually, that was the main reason why I used Edge as my one and only browser. 

Edge Chromium however desperately needs to be more touch friendly so that it can be used on touch screen devices and Windows tablets. Other than the improvement of scrolling and zooming, it needs the other features of Edge that made it super touch friendly. For example, taping on the menu button will open a larger menu compared to clicking on it by the mouse. Also, the fact that we could see the taskbar and the upper edge of the window with a little swipe was so useful. Let's say you're watching a YouTube video in fullscreen on your Windows tablet with touchscreen and you want to know what time it is, you can't view the taskbar anymore with the new Edge unless you exit out of fullscreen, and this is also a problem. You can't exit full screen unless you tap and hold the upper area of the screen which I bet most users don't even know about.
