DEV,
you're right, the functionality in the Eclipse Designer is not a full equivalent of the Modeller at the moment. This is because the Designer is in its early stages and we are still working hard to add functionality so it maps more fully to the capabilities of the Modeller. Features are added as soon as we have created and tested them and at the moment our release planning is decoupled from Activiti's own planning, so we may update released versions in a different schedule. If you're interested in running the most recent builds, the best way to do this is to check out the designer from version control and build it yourself. I should warn though, that you might run into issues if you choose to do this.
