"Change signals/slots" behaviour non obvious to new users.

Slight usability issue to consider :

A user new to Qt Creator reported that adding a slot via the "Change signals/slots" action in the context menu of a form did not create the slot in his c++ code.

They created a slot in that dialog and wondered why it was not visible in the "Go to slot" context menu action.

The "Change signals/slots" action seems to be left over from when designer was a separate product - is it still used often enough to be in the context menu?

It would be nice if the "Signals/Slots of <...>" dialog either indicated that this was only in the form, or made it possible to add source code. So that custom slots could be used easily from the Configure Connection window in designer. That would give us more power to for example quickly connect different widgets to the same custom slot.
