Notification when timer hits zero

[Azrael3000]

First of all, thanks for the neat little tool.

I don't know how much work it is but it would be great to have the option to make it display a notification once the timer hits 0. I get carried away when coding and need something visual to catch my eye, otherwise I miss it too often.

I also would like to make a stronger notification. First I thought about the Volume.
I tried to make the sound louder using gnome js, but it uses the Meta.SoundPlayer and there is no option to change the volume.
I tried to use GSound as an alternative, but it does not work. It seems GSound is no longer part of the Gnome Shell.

So I was left with making the Soundfile itself louder, which I did.
Do you think the louder Sound would work for you as well?

A notification would not be too hard to implement as it seems: Notification
But it would require a configuration for people to turn it on/off.

I would also like this, especially since I have the dock hidden by default.
