In the matrix editor, a sweep selection is made by dragging the mouse pointer with button one held down to define a rectangular selection region which expands as you drag the mouse. Eventually if you drag to within a certain distance of either the left or right edge of the canvas (an "edge zone") the canvas automatically starts scrolling to bring the neighbouring out-of-view portion of the canvas into view.
The auto-scrolling behaviour is very useful during sweep selections if you want your selection to include objects which are out-of-view. Sometimes, however, you want to make a sweep selection of objects that are near the left or right edge of the canvas without selecting any out-of-view objects but you cannot do so because the canvas will always start scrolling when you drag up to any of the objects near the canvas edges. In this case, the auto-scrolling causes out-of-view objects to be selected as well, and, since there is no way to de-select objects from an overly large selection, it means you have to scroll back to your starting position and re-make your sweep selection. Suggestion: the "special edge zones" at the left and right edges of the canvas which trigger the start of auto-scrolling during sweep selections should be moved to be just outside the canvas touching its boundary, i.e. the lefthand(righthand) special edge zone should be moved slightly further to the left(right). This change would not make it any harder to use sweep selections in the case that you want to select both in-view and out-of-view objects. The only consequence would be to make it easier to select just in-view objects.
