I pulled a big chunk of the feature requests with the most votes. I grabbed 164. Of those 22 were marked as done. 13%. These are the top 50 that are still not done although some of them have a workaround, are in process, or are almost there.

When you have your top requests sitting in limbo for over EIGHT YEARS, it kind of makes the whole āvote for what you wantā thingie a joke. Audio book support has over 1,400 votes and all it would take is album level resume and we can do it. Thatās it. Prologue can do it but you canāt?
People always (never) wished for that!
