Locking of Series in Comic Zeal and Pages and Notebooks in ThinkBook has been a very requested feature. As a developer my instinct has been to create as tight and secure a locking mechanism as possible and because it is so much work it just hasn't happened.
Lately I've been thinking more and more about how many weaknesses any system would have, no mater how secure I tried to make it.
Lots of other little things you’ll see in the change log too.
Changes: much better looking, and faster thumbnails. Much, much better algorithm for detecting the series name in a comic name.
Comic Zeal 6.1.4 has been approved by Apple and should be available for download worldwide soon.
