Eclipse thoughts

It would be helpful if //TODO comments were added to Tasks like in JDT (maybe better yet to mylyn tasks?!)
Also very helpful would be call hierarchy (and scaladoc integration).

P.S. There's a neat plugin for eclipse called ispace that shows you a graphical view of your project's interdependencies. Members are boxes inside containers etc., showing hierarchy, and lines show references from one location to another. You can collapse groups, and you can view dependencies on the macro level, e.g. from package to package, or you can keep drilling down until you see which member(s) refer to xyz. I found it very useful.
It registers itself as the viewer for files of type *.ispace, and it generates the file when the Java builder runs, but it has a very simple API so you can greate graphs from any other language.
I was looking into writing a compiler plugin to generate a dependency graph. I played around with plugintemplate and TreeBrowsers, and browsed the compiler scaladocs.
However, I'm still not so clear on how to take out of a tree that member x in class y in package z references member a in class b in package c. If someone could give me some pointers I'd appreciate it.
Thanks for a great tool!
