The Reply Separator Tag is placed into a div with style="display".There are two issues with this we think:1/ Thunderbird (and maybe other email clients) strip out this part when emails are viewed as HTML rendering this feature useless.2/ If this text is hidden but present in the reply, then users may put their replies below that line and have their replies stripped out in osTicket.I can't see the reason for trying to hide this line? I think the Reply Separator Tag should always be visible to users for it to be effective.
