Nice one! I know it's a feature we're also looking at for Slothbuzz.com!
I hadn't considered a notification when activating it. Maybe it doesn't require a notification, but rather a screen showing your previous votes in a list, for example. Should be easier to manage than a notification after each event.
Maybe both of those would be an idea.
I like to give users as close to full control as possible, without making it too overwhelming... or at least, that's what I'm hoping for 😂
