Thanks.
I tried to apply the patch, but was not successful ("The patch does not apply cleanly ... Patching is not possible"). I split it into the individual file parts, and managed to patch spkt_Const, spkToolbar and spkt_Appearance as well as the demo. As for the AppearanceEditor, however, the patch file contains a note for the lfm file saying "Cannot display: file marked as a binary type.".
Could you please try to create the patch again for the appearance editor again? As an exception add also the full files, if there is such an issue again.
