- Class Hierarchy Browser (by switching to that perspective all .st-files would get parsed to an ecore-model)
- Debugger (it's already there)
- Transcript (a console, it's already there too)
- a Workspace (we could use something like the eclipse-scrapbook-pages for that)
The viewer has two tabs. You can switch between the source view with syntax coloring and code completition and the class view, where you can select from a list of methods and see the associated method-source.
