I would like the ability to (more) easily comment out the current action with a single click. Currently the method is to add a comment action, then tuck the target action underneath. This takes quite a few clicks for such a simplistic task. Also, it clutters the interface a bit.

A good place for this new “comment” icon, would be just to the right of the delete (trash can) icon that appears on the left side of the UI when an action is selected.

Of course by commenting the current action, all child actions would become inactive as well.
