One of the biggest problems I have with annotations is that they are always placed with a yellow color. This is fine on black backgrounds, but on white / light colours the annotations are almost invisible. The only way around this right now is to continually poll the Annotation List propertyand try to determine if a new annotation has been added and then set its color accordingly.
A *WAY* better solution would be to either be able to set the defaults ahead of time, or, as the title of this idea suggests, add an event called Annotation Change or something that could allow us to determine if somebody had added an annotation / changed an existing annotation, etc. This way we could catch the newly created, practically invisible, annotation creation and set it to a more reasonable colour, etc.
