Gem Invades

Nice game. A couple of additional things would be great:
1. When I manage to clear a column and it is not refilled it would be nice if the next column pushed into its place. Not only is this a nice reward for the feat but you are handicapped for matches on either side when a column is missing.
2. It would be nice if matches for the same colour in different directions were noticed. I can often make T and L shapes and it is annoying that only one direction (usually horizontal) will match when I am actually trying to get the vertical match.
