Research — Navigation with scrolling, panning, zooming?

[Martin-Pitt]

Let me know if you would like to use native scrolling on the Research tree, or if you would want to be able to zoom and/or drag the window around, like you are moving on google maps or like in the game (the game has very awkward zooming imho though).

I think it's fine on mobile for now, but I can see wanting to pinch zoom out to see more all at once and making the dragging more smoothly along the diagonal, since native mobile scrolling tends to prefer locking you in one axis.

On windows it's probably awkward if you aren't familiar with horizontal scrolling, like using the middle mouse click scroll widget.
