Of course comment editing, for srs. Even if it's only for paid accounts, that's fine with me. Thread tracking, yes.
I also really, really want the DW feature where you can rename icons without breaking them on old threads, and
I would love it if the subject line would be the title of the page instead of gibberish. You know what I mean? Right now the title of this page is "http://asylums.insanejournal.com/marina_ooc/294494.html?thread=13546846#t13546846" and I don't know about you but I have no way of knowing what that is, so I had to install a new add-on just so I could rename tabs so I'd know which tabs were which posts.
