Actually, so you dont want to add my requested "feature"? Or cant you follow my opinion?
Here could be another feature request. You are familiar with Xcode code navigation. The is a drop down to see and navigate to all the methods in the file.

Maybe this gives the user a nice overview? I know there is a difference between visual overview and the drop down overview thing. But what about that?
Yes I know the snapping. But I have to do it. That the annoying part
Sometime if I scroll through my code. And then is a pain to pinch it up to 100% again. I never want to zoom in my code. Mostly if it's to small ill change the font size. The iPad 3 is so sharp that there is no need for that. Yes you might think "and what about the ipad1/2 users?". Me as a user don't care I don't want to zoom.

I assume that you have a trivial cause why you implemented zooming. But I don't understand why. At my productive Mac on my table I never use zooming.

I hope you will understand opinion
