[otrs] HTML Replys

I asked this earlier, but i cant find a reply, or the message in the archives, so maybe it got lost in the ether... 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.
