For 2, it may not be easy to fix, there is a preventDefault in action: https://github.com/anitasv/zoom/blob/master/zoom.js#L316 You can try removing it and see how it works for you. This was...

For 1: Check if this demo is working on your device: http://anitasv.github.io/zoom/zoom_2.html

Can you try 1.0.6 version, perhaps regression in the recent changes.

Oh that way; pan:false use to remove only single button panning. I can see this can be added.

That may not work, try setting t = 0 https://github.com/anitasv/zoom/blob/master/zoom.js#L180

You may want option to fix origin of transformation also. Like zoom from mid point or zoom from top etc. Otherwise multiple zoom events can do same effect as paning.

Sure, send me a pull request.

On it!

Done, let me know if it works for you now.

You can do this if you keep track of zoom in rotscale function, would you like to attempt?
