A two-dimensional canvas onto which heterogenic objects of various types may be arranged side-by-side. Each type of object has an associated set of control(s), the control(s) at least partially differing from one type to the next. The two-dimensional canvas is fixed in one dimension, but extensible in a second dimension. The canvas may be displayed in miniaturized for with a view box superimposed upon the canvas. As the view box is moved over the miniaturized canvas, the enlarged editable portion of the corresponding canvas is displayed in an edit view. The canvas may also display clusters of objects that are arranged in dashboards. In that case, the display might include a dashboard review area that allows a user to select the appropriate dashboard to display.
