multiple corrections

Hello,
Since I have to develop a library of over 33 thousand books, in order to facilitate my work and, I imagine, also that of many others, can I ask that the following changes be made to Caliber and that they act on all the selected books?
- when editing the metadata, insert a row to clear the Ids fields.
- activate a function that changes the "preserveAspectRatio" fields from "none" to "yes".
- the possibility of removing all the integrated fonts and changing them to another font.
Thank you very much.
Best regards,
Gianni
