help users in making changes to layout

Question

When an automatic layout is applied to a graph, edges are often represented as polylines. If the user drags a node, only the last segment of the edges connected to it is dragged. This results in an awful drawing, which requires the user to drag also the other joints of all the moved edges. To see this, draw any graph, apply the tree layout and then drag any node that is connected to others with edges that are not straight.
 The feature request is to drag along entire edges, not only their last segment, and even better, to use bezier curves.

Answer 1

You can move bends and nodes together. Select the nodes you want to move, then use the selection marquee to enclose the connecting edges (while holding down SHIFT). This will result in the bends of those edges being selected together with the initial node selection.
