I'm soooo happy to have a way to get multiple snooze options back. Thank you!
One problem I've encountered, is that sometimes the app doesn't seem to be active (I get no notifications), even though the menu bar item is still present. I have to quit and reopen to get it to work again. Also, I'm not sure the "start on login" makes it truly start, again it looks open, but not active. I explicitly added it to my login items, so perhaps that will work.
One suggestion: make the notification box a little smaller, or even customizable. It's a bit too distracting as is.
