Since connections are drawn on top of one another, it is not always easy to tell. This is a problem that many people using Zest have faced. To assist with this, I have added a new API on GraphConnection. You can now call GraphConnection#setDepth to curve the connections.
GraphSnippet11 shows how this API can be used. I still have to add the functionality to the JFace viewer, but the functionality should be there by the time M4 comes out.
