Playing around with the tool, I've ended up in situations where I was unable to close the properties window because either I had to give a (unique) name to the object despite not changing the name or getting a protected attribute error despite not adding any attributes.
Therefore, I think there should be a OK/CANCEL option for this window, with X cancelling all changes. This also helps undo undesired changes (such as overwriting a complex expression).,
