Simon, Regarding the first quote: Great! Regarding the second quote: If you simply want to view and edit the code of the designer in your workspace, this is the only project you have to checkout... Regarding the third quote: Starting the 'Eclipse Runtime Workbench' is for testing the modifications I mentioned in 'regarding the second quote'... It is done by choosing 'Run...' and then creating a new Eclipse Application launch configuration. Are you familiar with this?
