Dragging a dimension's label moves the dimension: a linear one slides
out from the drawing (never onto it) and its label along the line, an
inline one slides its label, a leader's label goes anywhere and the
leader follows. A click without dragging still opens the editor.
The preview zooms with the wheel, pans with the middle button and fits
again with F or a middle double-click. Once zoomed or panned by hand,
parameter edits keep the view; a new shape or configuration fits it and
puts dragged dimensions back. An open editor follows its label.
