Which feature must I install for org.eclipse.zest?

Dear lazyweb!

I have been trying to figure out which Eclipse 3.4 feature I must install from the update site to get the org.eclipse.zest plugin in my environment.

I installed the Zest feature (which I am going to use to visualize an RDF network), but my workspace still complained that I did not have the plugin.

Maybe I should rerun Set Target Platform for our product, but I and others in the Bioclipse development community have been wondering how we can know what feature to install via the Software Updates... to get a particular plugin on your machine?

Looking forward to hearing from you,

Kind regards,

Egon
