I hope in the next version it is possible to place the chord symbols under the staff.
Now it is already possible to insert the lyrics text above or below the staff, if it were possible this also for the chord symbols would it be fantastic!
Unfortunately it’s very hard move manually chord symbol in Engrave Mode, but it is the only possibility and the result is not very precise.
in Italy it is typical to do the scores like that (see the attachment example)
Thank you very much!
