An improvement request: I de-obfuscate embedded fonts as I only use freely licenced fonts, which Indesign unhelpfully obfuscates. Is there any possibility of adding a way of setting obfuscation options for all fonts in the epub at once? When selecting multiple fonts the options are grayed out even if all fonts have the same obfuscation settings. In my case it might also be a preference option. And I consulted the user guide this time, honestly
@kiwidude: Font de-obfuscation might also be a useful option for Modify epub, if Calibre has an API for it? I couldn't find one, or I would have given it a go myself.
