Would you mind listing the missing features in the current Lucidor that you want to have implemented in a new release?
For starters, I was thinking of adding some EPUB 3 capabilities.
That would be my choice. Thus far, Lucidor/Lucifox have displayed what I have brought up in them, but that's hardly a representative selection of the ePub universe.
My understanding of the spec is that graceful degradation is mandated, with things not supported by a particular viewer implementation simply not displayed. (So an embedded video or audio clip might not be available on a a dedicated reader, but the text and static images would display as intended.)
