Jay We purposefully disabled zooming/expanding/collapsing while editing because we were afraid of accidental taps while editing. Do you think it would be better to allow them through?
For me personally, accidentally getting into the editing mode while trying to expand / collapse / zoom a particular node happens far more often than the other way round. This is because of the relatively tiny “arrow” button on the right extreme of the mobile screen that is used to expand / collapse a node.
I would say it would enhance the user experience if zooming / expanding / collapsing is allowed while editing.
Also, thank you for this awesome app that has been thoughtfully designed.
