Speaking of the pathing interface, I also have noticed that if I give a unit a multi-tile movement order, the scouting is done only on the tile that the unit arrives at, not the entire path. Highly annoying for scouting diagonally, necessitating clicking on every tile (or just about) in order to avoid leaving scouting gaps, especially at the 'edges' of the path.
For example, consider this scouting 'display':
ooxxx
oXxfx
xxpxx
xsxXo
xxxoo
where 's' is the starting tile, 'f' is the finishing tile, and 'x' is the area actually scouted. 'X' is the area that would have been scouted at point 'p' but is not.
