Comment 7 for bug 760103

The blue corner's meaning is totally unclear. I thought it meant there's something on the Unity menu that required my attention, not an application on the bar.

It is the arrow(s) to the left of an application's icon that indicate(s) that an application is running that should turn blue when a given application requires attention.

I propose the following behaviour:

1. The application’s arrow(s) turn(s) blue (the one(s) to the left of the icon).
2. If the bar is auto-hiding, the arrow(s) should pulsate at the same speed as application icons now do for as long as the bar remains visible.
3. If the bar is always visible, the arrow(s) should pulsate twice every 5 seconds.
