Is there really no supported Eclipse Plug-In for Mono?

Question

I am a happy user of the .Net Framework, but since one year I am also a happy OS X user. Mostly for development I reboot using Windows for developing .NET stuff. Just I tried the first time Mono Develop and find there are many cool things like MonoMac (I didn't try them already but it seems to be quite funny).

But trying MonoDevelop for one hour I had 2 crashes (while moving a file). Right now I am asking my self why did the Mono team creates a new IDE instead of creating a good Plug-In for such a cool IDE like Eclipse?

Searching on Google returns 3 or 4 projects but it doesn't seem they're really supported...

Right?
