the Tile View mode Network Viewer is really nice, except that if you "u"p then "d"own into the network that has the operator set to network viewer, the tile view reset to some absurd zoom and origin.
It would really - really - be nice if I could set up some operators in network view by setting the size of the operator, positioning the tile view to frame the network view I want, then know that as I navitage and come back to the same place I will be able to see the same network view instead of some small details of it.
