I'm finding Roll20s support for touch screens really lacking in 2019. Being able to quickly markup a map using my finger (or Pen) during a game would be really useful but at the moment, Roll20 refuses to even respond to touch input when trying this. I have to use a mouse/touchpad which is frankly really awkward. For reference, the device I'm using is a Pixel Slate running ChromeOS (although I had similar issues with using another Chromebook, the Asus C302 which was also a touchscreen device). Given that its 2019 and touchscreens are here to stay, I think its high time that Roll20 improved its touchscreen support. As an added bonus, responding to the Pixel Pen would be great too. Haven't tried it with a Surface Pen since my Surface Pro 2017 is no longer a device I use on a regular basis.
