Ticket #8721 (closed enhancement: fixed)
Please add support for Mobi EXTH metadata data in fields 113 and 501

Any non-Amazon .mobi files can easily be updated to use the "Sync to Furthest Page Read" feature. It's only required that EXTH 113 be populated with ASIN data (and UUIDs have been tested and seem to work as possible values, if you wanted to have Calibre auto-generate them) and EXTH 501 be set to "EBOK". If a value is currently set for EXTH 113, Calibre should honor that. If no value is set, Calibre could auto-generate one when the file is a)added to the library or b)created during a conversion.
Eventually users might want access to EXTH 113 (ASIN) in the Calibre UI, so they can match it to the actual book. As a stopgap measure, using a randomly generated number, such as a UUID, should be fine. Mobi2Mobi can still be used if users want to modify that field for now.
