Hi All, I would like to know how we can modify the Rules flow eclipse editor look and feel and functionality. e.g. If we have a Embedded Sub-Process in the flow and reduce the size of it, the arrows are still displayed in the main canvas. Please see the attached snapshot for reference. How we can fix it? also if we want to open the Embedded Sub-Process in a new window for easy maintainability/readability of the very complex processes, how we can achieve it?    Going forward we are also looking to create the custom editor for the nodes. Please guide us if its possible and there is any document for this.   Regards, Prafull
