The EMF Forms project has contributed another Ecore editor (see http://eclipsesource.com/blogs/tutorials/emf-forms-editors/#ecoreeditor), named Ecore Editor in Eclipse. This editor is based on the default one and hence is tree-based, but has its own pane for properties that has been tailored for Ecore with special attention to what attributes are most commonly edited.

The same model as above is shown right, and as can be seen, some attributes have been "promoted" to the Standard group of properties, while others are in the Advanced group. This is particularly helpful for novices, as it helps to focus on the most relevant attributes.
