Hi Kris,
I've just installed Marvin 3 and done a backup/restore of my old Marvin library into it. So far I am very impressed but have one issue that I hope can be cured.
Bringing up a list of books under old Marvin the mini covers can be flagged as unread (* on red background), read (tick on blue background) or being read (no flag). Under Marvin 3 these flags should be able to appear as swiping the book brings up the options to do this. My restored library shows these flags are set.
But the flags don't appear on the mini book cover. Even when I turn them on after swiping, these don't appear. Is this a bug, or hasn't this been implemented? If it should work is there an option in the settings I can turn on to make the flags appear, I've searched the extensive Marvin 3 settings and so far I haven't found anything.
Also any news on the Calibre sync plugin yet? I really miss that after the IOS 8.3 release broke it.
Apart from these issues I really love the new Marvin 3, great job.
