Can you make single finger zoom work?

Hi there, in most apps you can double tap then slide up and down to zoom in. Would it be possible to add to this app as well?

Thanks!

Really? I've never done this.
- I have limited mobility at times and having that is quite a bit easier than having to set the phone down to use two finger, or need two hands to do it.
- Don't take this as a competition thing, but the jeroba app has this if you wanted to test it out.
