#13 "Cancel" button

[Ralf Lehmann]

As I noticed, there is no "Cancel" button for all the
dialogs which makes it difficult to cancel the most
recent value changes. I understand that we have
the "Restore" button but that is not quite the same as
being able to discard changes.

BTW, changes are always applied even when I close a
dialog "the hard way" via the "Close" icon or the system
menu of a specific window (dialog). That's how it works
on Windows(tm) ;) at least.
I have no idea if this is fixable, though...
