New Krypton and Things Done Right

Recently, I have been reading the New Krypton storyline.

This is a small crossover event that is being handled really well by DC.

"How?", you might ask. Well, I will tell you. They are numbering the order in which they occur on every issue that involves the story. On every cover there is a small diamond/shield shape with a number on it.

That is elegantly simply. More crossovers (especially the larger ones) should do this as well.
