Can selectionOnDrag be dynamically toggled with a UI? I want it to behave differently on touch devices vs desktops.

It can be toggled, but it doesn't work on touch devices. We will check how we can fix it.

Yea, I managed to toggle it myself, but would be nice if toggle was built-in since selectionDrag can't work on all devices.
