Ability to cancel an abandoned edit when invoked from within LRC

After opening the Topaz editor from within LRC via the Edit In… command, I sometimes need to abandon the attempted change. If I cancel the edit, Topaz often refuses to edit because I’ve made no changes, or when I explicitly cancel, a duplicate image (the copy) remains in LRC. Topaz should either automatically deleted the unchanged copy, or offer to delete it if you’re too nervous to do it automatically. This option obviously shouldn’t be offered if I’ve elected to edit the original.
