I built a crystal radio as a kid. As I remember it, you make a

I was able to build a crystal radio from XO, wire, cardboard, plastic sheet and

FWIW, this is the "font-sizing code" I ended up using in my three activities
(OurMusic, SunMoonMusic and FileMix). It is contained near the beginning of the
csndsugui.py module.
It contains an option for the user to resize text in the given activity for the

of the more useful features.
A spinbutton is not IMHO a good interface to change the zoom level, but I am
not sure, that's the reason
why I asked to the UI team. Another option is add a button to set the zoom
