The odt2daisy export dialogue prompts the user to input or change a number of metadata fields and conversion parameters:
* user alternate level markup
* include page numbers
* include CSS
* Apply fix routines
* Apply sentence detection
It would be more efficient for the user if these settings were saved as metadata in the ODF file. This way, users would not need to re-enter the same data again when re-exporting the same file with the same (or very similar) settings.
(I wll try to write a patch for this.)
