Oh, yes, forgot about it. On tablet it could be pretty convenient to use, if it works. Thank you!

On my iPad, the vertical movements seem to trigger the page scroll

I've pushed a simple fix.

It allows to draw on touch devices (with interesting effects with multi-touch). But one can stuck at the center of the canvas. If it happens — tap the header of the browser to scroll back to top.

Could you please try it again?

Thinking about more elegant solution.

Much better now. Thanks for fixing it!

Thank you!

Thank you, working on it at the moment.
