I would assume that I am not the only person who has chosen a scheme but later on decided that it would have been better to use a different style. While new notes can be donned with the new style, changing manually the style of each individual note in a large annotation file is daunting and dissuasive.
I wonder if an option to apply style to all notes could not be implemented and added to the style options if it is not already part of the new annotation system that should find its way to the desktop sometimes in 2018.
