True... in fact I wrote those methods myself in n7y, so I should have done 
better this time as well ;)

Oh, wait... I mistakenly thought you needed to call the method again when 
toggling the action. Indeed you can determine the heuristics of the 'main' 
GUI item.

That would be:

- If the main item has no icon the checked state has none either.
- If the main item has an icon and the checked one has not, the item stays the
  same
- If both provide an icon, the appropriate one is shown

Fine with me :)
