It seems that whilst this Add-on replaces the content of a post, it doesn't seem to replace anything in Signatures. Is there any chance that this could be added at all please?? Also, in my case, sometimes people use abbreviations which are replaced, with a "/" between them (e.g. TZ/TAF/Wh2o). Whilst this add-on finds the letters if on their own with a space, is there any chance that the functionality could be added where a user defined character can be used as a demarcation between replacements??
