Hi again,
First of all, the switch allows you to decide if the rheostat only controls the brightness of the AoA number band or also the emergency compass and the G-meter. The clock is illuminated by one of the map lights.
About the comments from devs and other questions, we try to always take a look and we take into account all reports that are posted here. Some, like this one are easy to check and, if needed, correct. Other topics might be more complex and require more testing/questions to SMEs and further investigation or development and we prefer to not comment anything until we have a clear picture. As always, videos and tracks are very welcome whenever an issue is being reported and help facilitate our job.
