hi looseleaf I'm a bit confused to the "touch to scroll feature" you described as we never had this feature? I just tested on the old version on both Win8/Win10 with fit to width and tapping left/right side of the screen advances to the next page. If you are talking about the missing vertical scroll bar you can scroll with the mouse wheel since the last hotfix (1.2.1.0, new canvas does not have scrollbar), but touch was never supported on the scrollbar unless you had a mouse to intervene.
Regardless this is a very easy feature to add with the new canvas we'll add it as an setting so you can turn this on in the next version! (expect it in 1-2 weeks).
I hope this helps!
edit: I think I know what you are talking about now. Are are asking to "snap" to only vertical scroll, if your finger generally moves in a vertical direction? If that's the case this is a one line code change, we'll add this back soon. I would also suggest using our new top to bottom reading direction to avoid this problem in the meantime.
