User request to enhance use of Rubberband Section (click and drag your mouse over the more than one shape to select) to not include the selection of connector lines.
This is preferred because 1) With the line selected you cannot use the alignment menu 2) With the line selected small "+" appear on the stage making movement of the selected shapes difficult and 3) It would make the rubberband selection more like selecting multiple shapes using CTRL+left mouse click (by moving the shape and the connected line, without requiring the line to be selected).
To reproduce:
Try selecting 2 shapes (rounded rectangle and cylinder with a connection line between them in my case) with CTRL+left mouse click. You only see little blue rectangles on the sides of both shapes.
Now do the same using rubber band (click and drag your mouse over the shapes). Now all other shapes show small blue plus signs, making it very confusing to validate if the selection worked. Click and drag does work, however, it is noisy on the screen. Additionally, the align tools are not visible on the right hand side.
