Be sure to hit them with at least one support ticket per missing feature. I would really love Wire to succeed (they're doing very well so far, security- and usability-wise) and they do respond to support tickets. So far, for me, nothing ever came of my bug reports (for example, `markdown preformatted text` still sometimes clashes with the url parser), but I expect that if multiple people report the same thing, they'll give it some priority.
