Up to AC 12 when I mirrored the Label Tool the text alignment would mirror as well. Meaning that if the text was aligned left and I mirrored the note the text would now be aligned right.
I saw this as the correct behavior because if I had the text aligned to the arrow I still wanted it aligned to the arrow when mirrored. Now on AC13 it is not mirroring the alignment so every time I mirror a note I have to fix the text. Is there a new setting in AC13 I've missed that I can adjust to get the previous behavior back?
