Is there something better than Monodevelop?

I have numerous Monodevelop issues. see here: http://answers.unity3d.com/questions/44064/is-monodevelop-find-in-files-supposed-to-be-this-slow

I just wanted to know if there were any other options. My main needs are:

-document browsing (so I can see all thye function names) -back/forward to last piece of code history. -a search system that works. -that it works with Unity

I dont care about autocomplete or any other gimmicks ;)
