[Moose-dev] Roassal: Lines and Arrows

Hi all, I'd like to customize lines with arrows a little bit more than seems to be possible out of the box at the moment and am looking for some pointers. I have attached a screenshot to explain what I'd like to achieve. I'd like to be able to: 1. Define a certain distance from the arrows beginning and end to the objects they are attached to - so they are not directly 'glued' to the objects. 2. Make lines wider, without just affecting the width of the line (and in the same extend the line the arrow is made up), but instead it should scale to nice looking arrows. 3. To place lines besides each other from and to the same object. Are some of these points already possible but I missed them? How would I best go on about modifying, extending Roassal to allow for edge styling in this way? Cheers, Dennis
