It's an incredible product as-is, but I feel like they are stuck between a rock and a hard place with moving forward and forecasting beyond the immediate future.

I don't see why a new implementation couldn't maintain the current UI/native feel outside of poor decision making.

I could see it as a net positive, with cleaner easier to maintain code base built on more recent tech that is more accommodating to younger developers.

If they could pull off what Atom.io/Github did for the old ingrained IDE world in a mail client, that would be incredible, IMO.
