Same applies to the twist field.

 Issue 657579  has been merged into this issue.

IMHO we should probably add this only when hooking it up on at least one platform.  IIRC we had some hardware/OS combination which supported these (was it the Wacom on Mac perhaps?).

I agree it's not very high priority, but perhaps it's pretty easy to do and so still worth doing soon?  Navid, do you want to mark this Available to see if anyone else is interested in picking it up?

This is something that Lan will be working on I believe. I believe there was another similar issue for this that was assigned to her anyway. I assigned this to her for now.

 Issue 657580  has been merged into this issue.

Can this be marked as fixed now?

We also possibly add 'twist' in Android, using MotionEvent.AXIS_RZ values. But we should wait until we have devices reporting it.

Let's close this bug, we will open another when needed for Android.
