Added event based display changes for big font view: It is now possible to activate "Autofocus" option in custom view dialog. This enables automatic switching of the current view depending on current dive situation. Because T7 view already displays a lot of information this feature targets the T3 view.

Heinrichs Weikamp OSTC4 update files.

The builds are for testing purposes only. Be careful, they might not work and are definitely not recommended for real dives.
