This update fixes the issue identified by Issabella and problems encountered when using with thin character layers.
It also adds an option to add ghost characters above and below the original character.
Personally I think this works better when the character is in front of the ghosts but if you use the other option I would suggest lowering the opacity of the ghost layers.



Download, unzip and place in your Gimp 2.10 user plug-in folder.



Examples of the new option:
