Ability to change the font size for network name and password could be nice.

Hi @olekstomek,

Cool idea. I'd be happy to review a pull request if you'd like to contribute the ability to change the font size.

Now I thought that it can be a big problem to put all the letters on the document if the text is enlargable (reference to #28). Perhaps this is the optimal solution at present - if someone wants to access the network, he must be close enough to read the letters or scan the qr code.

Considering the impact on #28, font size is probably best left outside of user control. An upper/lower limit could probably be worked out but the introduced complexity is likely greater than the value provided.
