Sure - but if they're a bunch of polygons, it might be more interesting.

I agree the map is the ultimate tool. However, I do think that being able
to quickly view a single geometry from within the grid makes a lot of sense
- and for users who want to easily visualise a single geometry, will be a
great deal more convenient than the map.

Note that I'm not talking about anything complex here - just a convenience
panel that renders the geometry, and maybe has zoom and scrolling. The
viewing tab would be where the real magic happens - handling the map
overlay and the ability to display many geometries at once.
