Jokes aside, it looks like the Zest project will finally make its way into GEF. This is great news for the GEF project along for people interested in creating visualizations in Eclipse. So, look forward to seeing Zest in GEF in the future, for now, feel free to browse the snippets.
It’s also important to note that Zest only depends on Draw2D which is tiny. I filed a bug against GEF to componetize the project a bit better so it’s easier to use Zest/Draw2D as they have minimal dependencies.
