Add a line to the compass heading dive menu that shows the currently set heading to enable the diver to confirm it / add it to notes. Also add a log entry every time a new compass heading is set or the heading is cleared. And add a way to add compass headings to the log without changing the currently set heading - this was added after discussion with cave divers who are interested in recording headings when mapping out caves.
