Added an "Order Miscellaneous Costs" column to the Performance and Order Items pages, treating order-item expenses such as reimbursements and refund fees like referral and FBA fees
Added a mouseover breakdown for each value (tax included for finalized transactions, product vs. store split for Other Expenses), available on the Order Items and Orders pages with more pages to follow
Improvements
Consolidated "Other Expenses (Product)" and "Other Expenses (Store)" into a single "Other Expenses" column so Expenses page totals match the Performance page
Stopped showing costs reclassified as Order Miscellaneous Costs on the Expenses page
Bug Fixes
Completed the cost-related data re-processing so all data now reflects the correct values
