[ubuntu] Right click and scrolling with touchscreens

I have a laptop with a touchscreen, and while the touchscreen works in Ubuntu 16.04, it's missing a couple of essential features. Namely an easy way to right click and and easy way to scroll. Is there currently a good solution to this?

Three and four finger gestures work fine, so the touchscreen itself works like it should.

Google Chrome supports drag to scroll, and I know there is a Grab and Drag addon for Firefox to do the same, but I would like to be able to scroll everywhere, including in the terminal, the Dash and more. Basically a gesture that behaves like the scroll wheel on a mouse, either using click and drag or two fingers to scroll.

Secondly, I haven't found a good way to right click. In Windows 10 and on Android, this would be click and hold. This seems like a good solution, but I haven't figured out how to get this working on Ubuntu.

Any suggestions?
