Problem: most editors when in browsing mode first click on the node they want to select - the next action is SEARCHING the checkbox/radio where to select the current node - then they realize that there is no such option and are confused. This is one of the Top annoyances of our editors.

Possible solution: place a checkbox or radio button not only in children list but also in the box next to the headline with the name of the current node (radio preselected, checkbox not selected).

This would spare the editor in most cases a break in the action of selecting an article (when wondering why he/she cannot select the current node) and an additional click.
