Can you make a video or a screenshot of this? Not entirely clear what is happening.
What do you mean by "thrown off the way"? Should we revisit the axis orientations in different camera views?
Yes, we should give more visual feedback for snapping.
To be honest, keeping the glass cleaner is not really a driver of product design in case of a multitouch device, where all the interactions are based on touch controls
And thanks for the feedback, much appreciated!
