Fred,
Great question and this is *exactly* why we added the ability to turn off portions of MyEclipse you aren't using under the Window > Preferences > General > Capabilities menu, you can click "Advanced" and effectively turn off the MyEclipse features you aren't using.
Over time we hope to break out MyEclipse into it's major functional pieces under the
Pulse provisioning system and allow folks to build it out piece-by-piece depending on what they want. That's still a ways off though and using the Capabilities menu will get you exactly what you want now.
