I find the beep to be most annoying, especially when I'm listening to music through my headphones. It would be nice to have an option to turn off the beep. Some plugins beep also, so I'm proposing adding a method to GUIUtilities so there is a standard place for everyone to request a beep and maybe people can retrofit the plugins to use it.
I have the same feeling.
My current workaround is: switch to screen flash by Mac OS setting

After some research, the best way to implement this is via the look and feel, so I'm adding the feature for this into the LookAndFeel plugin.
The JavaAssist plugin provided this funtionality for a while, but it's broken as of Java 9, I think. Regardless, it doesn't belong in the Look and Feel plugin.
