Zero file zupport (like in Agent) - text written in message editor in posts with attachments is posted in a separate zero file (00/00), so you can read the text, e.g. description of the attachment, without having to download the attachment first as you have to now.
Currrently the only alternative is to include a separate text or nfo file which is troublesome - much easier to write the text in the message editor.
Only one zero file per post of course, no matter if you include one attachment or one thousand.
An alternative could be that UE sent the text in the editor window in a seperate text or nfo file, or perhaps the ability to choose between the two options.
