Feature Request: adjustable sound volume while Tomighty is running a pomodoro

[Wojtek Dziejma]

I wonder if it would be difficult to add a volume setting for individual sounds, that would be effective "live", as a pomodoro is running.

My use cases are as follows. 

I sometimes do things that require concentration and I find the ticking distracting yet I would like it to be there, very quiet in the background, at the same time I need a loud bell at the end to remind me to stop reading.

I sometimes do video tutorials as part of my pomodoros, again, the ticking would be useful but just under the sound of the video, and with a loud bell at the end of a pomodoro.

Actually, you have to restart a pomodoro at the moment for any sound setting changes (on/off) to be effective, it would be great if you could just adjust the currently running pomodoro.

If you find the time, would it be possible to add this? Either way, thanks for a great little bit of software.
