Automatically switch between detached dashboard and map during navigation

I would like to propose a feature to improve battery life on OLED devices during navigation.

The idea is to keep a detached dashboard visible during normal riding. The dashboard could have a mostly black background and display essential information such as speed, distance to the next maneuver, remaining distance, and ETA. On OLED displays, this would significantly reduce power consumption compared to displaying the map continuously.

When approaching a navigation instruction, Locus Map would automatically switch from the detached dashboard to the map for a few seconds, allowing the rider to see the intersection or turn. After the maneuver has been completed, it would automatically switch back to the detached dashboard.

An optional setting could allow users to configure:

• when the map is shown (e.g. 100 m before a turn or 5–10 seconds before),
• how long it remains visible after the maneuver,
• whether this behavior is enabled only during turn-by-turn navigation.

I believe this would be especially useful for cyclists using OLED devices, where reducing display power consumption can noticeably extend battery life without sacrificing navigation convenience.
