Actually, it's been tested with Adminimize. (I even recommended using it in earlier versions.) I know it works with that plugin as far as not creating conflicts go. The most recent version of Back End Instructions, however, removed the *need* for it with this plugin - by popular request.
As for Ozh's dropdown menu, it may be popular (as Ozh's stuff is, naturally) but not everyone uses it (In fact, this is the first time I've ever heard of it.) So again, I *did* take into account possibilities, and I did provide a method to work around them.
Glad you're going to use my stylesheet to work around it, and glad you like the plugin :)
