I changed the sketcher weak dimension color from the light grey to light blue (same as Geometry, Centerline and Construction ) so users can see them better. I also set sketcher background color to straight black, not blended.
SYSTEM_BACKGROUND_COLOR 0.000000 0.000000 0.000000
ALIAS_SEC_DIM_WEAK_COLOR_TO SYSTEM_SECTION_COLOR
Reason for therse changes is because back in WF4 the dimensions had a black box around them which made it really easy to see when working with shaded models.
