I know this has been requested two years ago, but in the meantime it has hit 0.9 and is speeding towards version 1.0.
I think an alternative to Nvu/Kompozer would be welcome. Without wanting to revive the discussion on deadness/undeadness of Kompozer (see here and here), I'll still remind that the latest stable version is three and a half years old and now it's almost a year since the latest development version's release.
