Show countdown timer progress in Unity icon?

Dear Johannes and others,

Alarm clock is simple yet elegant application.

Thank you so much for your work!

I have one suggestion:

Is it possible to integrate a progress bar into the Unity icon so that it shows the progress of the countdown timer visually?

And example of how such a progress icon looks like can be seen here [1].

Thankfully,

~Robert
