The Ark Bible is an open-source Bible application project, that can be freely distributed tby anyone and to anyone for use in spreading God's Holy word. There are some functionality differences between the versions of the Bible in this project, and part of this help file's job is to detail some of those differences.
1. The Red Letter - Black Letter function is currently only available for the partially edited chapters in the Twenty-Fist Century Version of the Bible. Other hapters and versions will eventually be able to use this functionality also, but not today. The Red Letter - Black Letter button is not visible for this functionality for the other versions, so the disappearing funcitionality buttons are not an error.
2. The Paragraph Layout - Line Layout function is currently only available for the partially edited chapters in the Twenty-Fist Century Version of the Bible. Other versions will be able to eventually use this functionality also, but not today. The Paragraph Layout - Line Layout button is not visible for this functionality for the other versions, so the disappearing funcitionality buttons are not an error.
