New feature: make selected customviews persistent Add the set of selected customviews during dive time to the persistent settings. Nothing has changed to the menu, so a user still has to access the on/off page from the simulator or during an actual dive, but once changed here, the settings are preserved for later dives. It feels a bit as waste of menu space to add a second page for something that is already available. And further, I have to admit the adding a page is rather complex to get the navigation right, so that is a 2nd argument not to add a page. Further, getting this one setting saved to the persist preferences is a bit of a hack. Misused an existing global bool value (WriteSettings) to force a actual write despite not being in surface mode.
