It is far from ideal, I agree. If you're coming down the hill to the station and just miss a green phase, it will take you 3 minutes to get across the street to the WH Smith. Not that I've timed it of course. OK, I have. This includes getting to the middle of the island and then waiting again as you'll just miss the green on the 2nd half of the crossing. Don't ever be late for a train, or this will mess with your schedule.

The downside is that if you fix the crossing timings, then you mess up the traffic and who wants more jams and pollution than we already have.

My vote would be for putting in a subway style crossing underground. Either that or put the whole Circular underground, see you on Dulwich Common.
