New style Box Indexes?

The box indexes would work better, and their purpose would be clearer if I drew them as Polygons, not as Lines.   Then

• Clicking anywhere in the box would work (except on a long track passing through)
• The boxes would be "greyed out" when in the World Index making it clearer that the box index had not yet been entered

There are about 25 boxes at present..............not impossible!  Well actually it was because the Index has stopped updating.
