Feature request: Quiz mode

[TheOneWhoseUsernameWasTaken]

Hello!

I'm not sure if this is outside the scope of what you're aiming for with this app, but I'd really like a quiz mode. Basically, the app presents you with a random set of resistor bands (let's say E96), and then you have to tell it what value that is.

It would help you learn how to read the values by yourself without having to fiddle with your phone every time. And it might even be a fun little game. It also might set this app apart from the rest, because I have looked for something like that, and I could not find it.

Just a suggestion though, thanks for your efforts either way.
