Note Editor Default font size question

[Mark Parent]

I have a note set that has a large amount of verses that were made in a default 9 font size. That's too small on my tablet editor for my older eyes. Iv'e changed the default size in the preferences menu to size 12, but that only works when making a new note set or a verse that has had no previous notes taken in the size 9. For the previous size 9 notes, i highlight the contents, resize to 12, and save. Is there a way to do this to all my size 9 notes at once. Can I open the user file by renaming to .txt and make the change to just the body of that file and change the extension back to .acc4 ? 

 

Thank you in advance!

I could really use some help here related to the question above. I don't understand what is happening. For new notes, on my Yosemite MacBook Pro desktop app, I enter a note in my user note file in text size 12. Then I sync with dropbox. Then I sync my windows 8.1 tablet and the note is there, but it is now font size 9. Conversely, if I enter a new note in my user note file on the windows 8.1 in font size 12, sync and then sync the Yosemite MacBook Pro app it is now font size 21 on the Macbook Pro. Does anybody have any idea what's happening? 

 

Both devices have the same preferences settings. User notes display "normal" and User Files Tahoma font size 12. 

 

Any help would be most appreciated.
