It would be nice if you could see how fast each galaxy is moving and in what direction.

You can see how fast they're moving away from us by their colour.

As for how fast they're moving sideways, nobody knows! But it's slow compared to how fast they're moving away from us. (Except for a very very small number of galaxies close to us.)
