Divina: add a visual signal indicating the reading progression direction

[llemeurfr]

The Divina player does not contain a visual signal indicating the reading progression direction, which can be ltr, rtl, ttb or even btt.

Is it possible to add it at the level of the app, or should it be a Divina player evolution?

After discussion with Florian, it appears preferable to build these indicators in the app itself, from the information given by the player.

As an overlay on the div containing the player, animated icons appear:

• a direction arrow indicating if the progression is ltr, rtl, ttb or bbt. It is associated with metadata/readingProgression.
• an icon indicating that the publication is continuous / scrolled or one indicating that it is discontinuous / tapped. It is associated with metadata/presentation/continuous.

The event containing the information about the reading progression is "dataparsing", sent by the player when starting.

Here are some samples of existing apps with such indicator:
