Change size of the text

[Dovahkinsl]

Is there a way to change the size of the text, make it bold and have overlines for antiparticles?
The default is barely readable as the letters have really thin lines

Unfortunately at the moment there isn't a way to change the size of the text. You can add overlines for antiparticles by wrapping the label in \anti ie \anti{\nu}.

I believe this is the main issue that stops this project from spreading to a larger audience.

I think this tool could be super useful, but I also feel the export PNG and PDF files are very hard to read. This is the main showstopper for me.

In my case the text was very large but I changed its size in the feynman.sty
