I always run any added book through the “Edit Book” function to check for problems, with a goal of achieving “No problems found”.

A lot of issues involve “CSS Property: Unknown Property” warnings such as “-webkit-text-fill-color” , “-epub-hyphens”, etc. I generally remove all these references.

Am I wasting my time? Would leaving these cause potential errors? Inversely, would there be benefit leaving them in for possible future epub implementation, or other reasons?

Thanks for any insights.
