wouldn’t it make sense to change the current Left Bleed / Right Bleed implementation to Inside Bleed / Outside Bleed. At the moment, it doesn’t seem to be possible (a) to design on spreads and (b) export to pages without adding a bleed area along the binding edge. See my schematic below. Exporting to pages will add bleed along the edges indicated by the red arrows.
However, as described in this thread, there are some print services that do not accept PDF documents due to this limitation and force the user to manually set up the document. This issue could be easily solved by adopting Inside Bleed / Outside Bleed instead of the current implementation. This is the more general setting which is suitable for a larger number of use cases.
Thank you for considering,
