Hi,
when we users need to change settings in a software we usually go under the menu Preferences which is very limited here.
There are important settings hidden under the Font menu.
Please leave the Font menu just for fonts and nothing else and put the other settings under Preferences.

Every time I forget this ireal pro peculiarity and waste time searching how to change theme or highlight rehearsal symbols, I'm quite sure that I'm not alone
..
Thank you
Daniele
