TL;DR
It would be cool if the taskbar button could blink on certain events, such as when research is complete, when the player is killed, or when a chat message is received.What ?
Most operating systems and desktop environments allow to get a notification from an application when an event occurs. For example, on Windows and some Linux DEs, the task bar blinks, on Mac OS the dock icon bounces. Some other games (for instance, World of Warcraft) use this feature to notify the player when something occurs to the player in the game when the game is not in focus (eg. minimized). Factorio could do that as well.I'm not really capable of recording such flashing myself, but this gif should illustrate it well enough:
