Freeze

 Sets a new initial state
 
The current state of a construction can be "frozen", i.e. the construction is saved internally. Objects as well as their properties and positions are recorded. The symbol   will be marked with a frame.

If objects are added, deleted or properties changed afterwards and after this  Defrost is clicked these changes disappear and the frozen state reappears.
Any clicking of  Freeze overwrites the last frozen state.
