A while back somebody showed me (Gareth Barnard) how they had changed the position of the arrows in Collapsed Topics from the left to the right. So I've thought this could be put in as a setting that would be easy to set just like the rest.
This is a simple modification that will integrate the feature for an easy way for users of the Collapsed Topics to toggle back and forth.
