Sometimes I want to select a point, but it is close to points from other, nearby shapes. I can zoom way in and click my point, but it takes too long to keep doing.
I suggest making it so that scrollong in the mouse wheel will cycle through points, lines, faces and what not that are within a user specified radius of distance to the thing the mouse is currently pointing to.

In this image the mouse is pointing at the line belonging to the grey shape. I want the line belonging to the brown shape. One mouse wheel "click" in either direction should switch the mouse selection to the brown shape's line.
I realize the example isn't fantastic as you could simply move the mouse to the brown shape's line, away from the grey shape, but see beyond the example.
Also the object that "has" the line I want should be clearly highlighted as well - so if I scroll the mouse wheel and get the the brown shape's line instead, the entire brown shape should become blue so I know that the line I can now select by left clicking is, in fact, belonging to the brown shape.
