Change width of cross-section by clicking on enclosing rectangle

On the main map window, a cross-section is depicted by an line down the center, with a rectangle that encloses all the events within the "width". (Actually, they are all arcs. Thank you ellipsoid.) .

One option would be to resize the cross section by dragging on the rectangle, or by clicking on the rectangle to choose a new width.

Currently, to change the width, right-click on the cross section's tab, and choose "change width" from the drop-down menu
