Change the font size of the tittle

I am reading a pdf book with many illustrations, equations, etc., so the overall mind map is quite small. But with the tittles being fixed size, it can be really inconvenient for me to navigate around my mind map, and the titles are seeming to be out of place:

I wish there could be an option for us to change the size of the title! Many thanks!

Hello, Tuo. This does seem to be an inconvenience, I’ll feed back to the developer.


Thanks so much for your reply. I’m just asking for smaller font options, hope that’s not too much trouble.
