In the order export it would be great to include :
- line item metas
- data about customer (LTV, # orders)
You can get line item meta already when the 'one row per line' export setting is enabled :) Customer stats are interesting. Don't think it will be possible for now though since they aren't stored yet but dynamically generated.
@Bryce Adams: that's great for line item meta I had not yet tried this option. Thanks Bryce
