I was going through a specific event and modifying emails as appropriate when suddenly I'm flipped into editing event templates without knowing it. It starts prompting me to save for current default template or for all upcoming events emails.

Something is confusing about the process here. How I got into modifying the templates instead of the event specific emails is beyond me. I believe you need to have much clearer designation that you are editing templates rather than specific event emails. Perhaps when going into edit templates, you could pop a warning that it is a template and not an event specific email first. Or figure out why it put me into template editing based on the navigation flow.
