Touchscreen support?

[bergi9]

Keyboard and mice support is clear. But what's about touchscreen support?
For example I have the Lenovo X1 Extreme notebook with 4k touchscreen. I tried to use the touchscreen with factorio and it doesn't fully support the GUI handling. For example the research-tree, scrollbar scrolls on touch but the content doesn't scroll on touch like on browsers (touchstart, touchmove, touchend).

I'm not saying to support player movement on touchscreen, just for GUI or similar.
I don't mean to force you to add support for it, just question if you (team) will ever do it or never.
