The Bible Study Builder is an amazing resource that has the potential to save us lots of time, however, being unable to change the font size at export/print time requires exporting to Word or Google Drive to do the font size customization and then most formatting has to be redone.
This is on the current Mac Desktop app, 47.0.
I can change the size via the 3 dot menu, but this seems to only be the size of the font in the print display and modal itself, not the actual exported document.
