Please make USGS quadrangle grid lines available as an overlay - for topo or any other format
Quadrangle grid outlines aren't always self-evident even on USGS topo maps. Since my projects are constrained by these grid lines, it's important for me to readily see this grid regardless of the map format I'm in. It should be an overlay. I just spent an inordinate amount of time forcing the grid over my mapping area via point-to-point line drawing. It was t-o-r-t-u-r-e. Given these lines are readily available, this should be an easy thing to do.

If you need a layer that indicates boundary of the USGS topographic maps, set a custom grid (File, Preferences, Custom Grid) to have coordinate spacing of 0deg, 7min, 30 seconds. Then enable Custom Grid in View, Layer Size/Visibility. Note also that the current quad name is displayed in the TNP titlebar.
This also has the advantage of being visible, regardless of scale and map type.
