1. Redesign whole GEF to avoid VERY HIGH coupling of different components
(Editors, Views, Edit Parts, Palette, Editor Domain). For now, everyone
knows about everyone. Introduce Mediator pattern which must be
listener of all components and actual Controller. Move all logic from
components to Mediator. In all components leave only plain code and
utility methods.

2. Create GEF UML diagrams for static relationships (Conceptual
model written with a help of Class Diagram) and for components
behavior (if all logic will be located in Mediator - only one diagram
needed! And it must be Statechart diagram!). Such set of diagrams will
help not only GEF users, but even GEF developers.

3. Explicitly emphasize states for such components as Tools and Edit
Parts. Visual state of Edit part must be prolongated to it's figure.
Whole state of Edit part must be superposition of underlaying model
element and visual state.

4. Write new good examples which will have all application logic in one
place (logic designer example has logic even in it's Figures! It's
incorrect and not clear).
