Actually canvas in the GMF-T generated diagram is always "infinite" in size and has free-flow layout, so that the nodes may be placed anywhere. However there is a lot of use cases where diagram canvas should have some visual structure. Right now the only way of implementing such use cases is to emulate this visual structure with the auxiliary top-level nodes. E.g: - State machine- like diagrams are forced to have single enclosing top-level node that contains all the contents. - It is very tricky or impossible to have additional visual elements that control the properties of canvas semantic element. E.g, in UML, the editable diagram name should be placed at the top-level corner of the diagram canvas, which is now hard to implement. - Dashboard- like diagrams would need to have some grid-based structure of the canvas and only allow to place the nodes according to the grid. - Compartments are only may be placed inside the nodes, there is no notion of the top-level compartments, which blocks support for the whole family of the diagrams similar to the Osterwalder's business canvas'es. This umbrella bugzilla is to cover the improvements in this area for Luna release.
