With Blink, allow popular apps to get their specific notification color.
This project is a 1 day project. If it doesn't work, I'm sorry, but I probably won't fix it since I have other things to work on, too.
There are no settings in the app, and no plans to add any yet. If you want a complete app, you'd better go for Light Flow or other free and paid alternatives.
If the app doesn't suit you, don't put a bad rating. Just delete it.
