[otrs] HTML replys

I'm sorry if i am repeating an earlier thread here, but all i could find was from some time ago. Has there been any progress with regard to viewing and sending HTML messages? Our customers frequently send us (embedded) screenshots, so a click to view for image attachments would be a suitable alternative to viewing the full html. Also it'd be nice to be able to append an html signature to messages, or insert a block of html to messages with some kind of markup tag. I'd be quite happy to try to code this functionality, but I haven't looked into how OTRS works yet, so any pointers would be hugely appreciated. W.
