Just a brain fart
What if there was a scan probe type that could scan down bookmarks?
One that just scans you to the middle of a grid that has boomarks on it. (finding the grid where offgrid bookmarks are. Maybe limit it to a corp or one character at a time)
The other just finds bookmarks on the current grid.
This may be a nullsec/WH only item because I could see this melting the server to a cinder if anyone ever used this in hi sec, let alone Jita.
