Plugin: Courtesy accidentals not working as I think it should
When using the plugin, I would think that once it has been configured to put the accidental in parentheses, that using the Add command from the first level of commands would follow that setup. However, that will insert the accidental, but without the parentheses. The only way to get them is to go back to the Configuration window, and use the Add button, there.
This has been confirmed on Windows, Mac, and on the forum.
