LOL, one more plugin that nightmares the life. :D The 1st time when I saw fewer hearts I wasn't sure what happened... some notification or visual would be great.
You may use the "verbose" flag in the config.yaml to show notifications. I'm not sure where's the tradeoff between "silence" and "notify about each change", so moved the decision into the config. Please share if you have a good idea of how to balance this.
