nUI already supports all of the Druid forms, it's just a pain that one of those bars also happens to be the bottom right action bar. For any other spec this is a non-issue, but for Druid's it is since that's their moonkin bar. The bottom line is that it is an "extra" bar for every other class/spec but unfortunately is not for a Druid.
There's actually a FAQ for this issue here:
