For those not already aware, the grid snapping is done in increments of 20. I don't know what this is 20 of, perhaps pixels, but it is 20 if I remember correctly.
When a new system is discovered it is placed, if possible, with a delta-x and delta-y from the connecting system of 140 or a multiple thereof. In other words the default spacing between systems is seven grid lines, a very strange number.
Given that most folks seem to not care much for the fineness of the current grid, I might suggest that the grid snapping be changed so that grid lines are spaced by 70 pixels. This would make a new system spacing of only two grid lines, easy to work with, and the intermediate grid lines can be used for a passable imitation of a triangular/hexagonal arrangement.
