1) Yeah, I think that makes sense. We'll add a command line parameter `
hide-email`. You'll need to download Spine again and reinstall once we've released a new launcher. I'll post here when we do.
2) True, I've also noticed this as being a little odd. I believe it's this way because showing an empty dopesheet isn't terribly useful, but I agree it would show the user there are no keys instead of the current behavior, which is to show all keys (assuming the dopesheet is not locked).
