Nice to see you started to improve Commerce, however, still do not see something I was requesting for years already - ability to adjust price after purchase basing on custom field value.
This is kind of a 'must be' feature for subscriptions. E.g. you make purchase of subscription of specified product, and later you may only increase count of licenses (using purchase custom field value) for that specified product (subscription) instead purchasing new copy of product (subscription) over and over. It looks more smooth for admin and customer. Ability to charge after purchase basing on change of value of purchase custom fields, opens a wide ability to manage products and subscription.
I honestly wonder why it is not yet there. Anyway, thanks for your work, hope to see such feature in near future, finally.
