Code has been completed to link the patch cables to the modules they are drawn on. This means that when a module is moved either within a rack, or across to another rack, the cables stay attached. There's no point showing a picture to illustrate this as it needs a video to do it justice (although in the pic below you can see that the Choices joystick is being moved and its connection to the left Plague Bearer is being maintained). I'll make a short vid at the weekend to show all progress to date.
I've added to the dropzone code to show not only how wide a module is, but also how big the gap you are failing to drop it into is.
