Hi G.,
Yes, I can see that they are omitted. I assume that most people apply shortcuts to them and don’t care about icons (Otherwise, there would be more requests for this.)
Three things can be done.
The best option is to check with the support; it should be a big problem to have them included.

The second version would be the way I would do it if I need an interface icon: Script-log [cleared], then call up the command one time and place the whole text from the script log into the Script Manager. Then set up two objects that show the Parent or Un-Parent idea, and render an Icon via Script manager. This new command can then be placed via Command Manager into your interface.

What I wouldn’t do, but what I have seen is a c4dr25_Missing_icons_fix_v01 (google it. Why wouldn’t I do this? Because I am too neurotic to place stuff from the web into my system.)
Cheers
