The font on your branches can be changed, you can use a mix of different fonts throughout your mind map. 

If you have started a new white board and you would like to use a different font for the whole board, you can change the font in the layout settings.

If you change the font on an existing whiteboard, it will affect all new sticky notes added after the change but it will not automatically change the font on existing sticky notes.
