I'm really pleased to hear that paper 1 was a nice one today and it seems most people left feeling very confident. Whilst I'm happy about this I do want to warn you that paper 2 probably won't be this easy. They normally have an easier and a harder paper and so please show full commitment with your revision right until the last paper has been sat and don't take anything for granted.
As promised, here is a list of the topics that did not come up on paper 1 today. They won't all come up on paper 2 but making sure you are comfortable with these topics in particular would be a wise decision.
Best of luck for paper 2 :-)
