I just installed the latest version from the website. But I had to put the backup back because the auto reply did not work with the downloaded latest version. So there is still an error in that version. I also tested the html in the frontend, but with that version the html is also showing in the frontend. So putting text on every line in the "Default text in the field" field, shows all the html in the frontend. So if I want to put a line with red text, the html is shown in the frontend. I don't believe that is what it is supposed to do.
Also we previously spoke about the field with the keywords. You say it is supposed to auto reply to any keyword in the field, but thinking about that, that is not a logical solution. Why would you make multiple lines possible? If you want to auto reply to a question, you never know the exact sentence someone is going to use. You would have to place every possible phrase in that field. It is much more logical that you can say that certain words need to be in the field for the auto reply to be sent.
Say you want to auto reply to a question that has been asked over and over again about how to set the default for refund on unpublish ticket. You don't know how that question will be asked, but if you have an auto reply that has to match all the keywords "refund", "unpublish", "ticket". You can make an auto reply for that question. The auto reply is now actualy useless since you can never send an auto reply for only one word or the exact sentence. That is nearly impossible to do.
