I don't really work with audio very much in Qtractor but if I did, I would never resort to using my eyes (which is what zooming lends itself to) in order to locate 0. I'd expect there to be a keybinding of sorts which could be used to "find (prev or next) points where 0 is crossed". If memory serves, these exist in Audicity? I'm sure someone here could elaborate in more detail if I'm mistaken or off. The general idea though is to expect the software to provide identification and navigation capabilities.
G3N-es, totally agree that having the ability to specify a "step size" for zoom increments would make sense as a global option.
