Slim down Eclipse context menus

I have several plugins (Apatana, SVN, Pydev, Zend Debugger, PHP) installed in my Eclipse 3.5.2 (Ubuntu 10.10) installation. The one problem that keeps bugging me since I first used Eclipse years ago is, that each plugin puts new entries into the context menus.

Unfortunately, it seems that the various perspectives are not able to determine, what menu entries are useless. So while programming PHP the menus are full of java and pydev stuff, I really have no use for!

The more plugins are installed the messier the menus get. It seems a bit odd, that such a rich IDE doesn't have support for context sensitive "context" menus ... :-(

My hope is, that somewhere out there on the internet, someone knows how to remove unused menu entries, or even has created a small plugin for that??

Any ideas?
