Indicator for Idle Heroes

Hello, quick simple suggestion from my side. I and I guess a lot of people would like to have a notification of some sort - button or popup when one or more of your heroes are full energy and Idle. Ideally this would be something that can be toggled on/off.
Great job on the site :slight_smile:


Would be great to see something like DFK Tracker move over to a mobile app, and then having this built into the app to allow for mobile push notifications!
