multiple instances support is a significant and very invasive development task (which I'm dealing with now with numerous iPad apps at my job) — personally, I would probably prefer that energy focused elsewhere within the app assuming good multi-pane support is forthcoming.
I'm not a dev, so I didn't realize how difficult that is. That's on Apple then. They should make that a simple switch that doesn't require a lot of work, so I will give Accordance a pass on this if this is accurate, and I have not reason to doubt you Rich. Just don't know personally. Thanks for the insight.
