Promotion question time: The current promotion system in Solidus is quite strict when it comes to discounts on completed orders: Adjustments are finalized and will never be recalculated, even if line items change (think a 10% discount off shirts, and you add or remove a shirt from an already discounted line item - the discount won't change). Has this been an issue for people here? If so: How did you imagine the system to work? E.g. "previously applied promotions should still apply and be recalculated", "we never change orders after completion", etc? For example, in our shop we have a thing where admins can add a promotion to an already completed order. What features are you missing?
