Hello, I've tagged this as an enhancement, maybe someone pick this one up or I will do it myself when I have some time

@Modest-as , thank you! I tried Pig’s experimental feature related to annotations and it did work. The only thing it did not provide is whether the annotation/comment has a border of particular color (red, green, etc) and whether the border is dotted or not.
