It would be interesting to engage a preference for no overlap in the key editor (piano roll).
Like everyone knows there is a setting to remove superposed notes in the key editor, but it would be a workflow enhancement to avoid doing this all the time. Of course someone can also make a Macro ro remove duplicated notes, but I guess is faster to have a checkbox in the settings for user who wish to have this feature ENGAGED all the time.
Thanks,
Francisco.
