I would like to suggest that the Radar Altimeter readout found in various Command Pods be viewable outside IVA by clicking somewhere on the Altimeter display at the top of the screen. I would like it to function in a similar way to Surface/Orbit/Target modes of the navball, where clicking the display will change it.
Radar altimeter functionality is already in the game, albeit in a place that makes it less than useful for most players. This would be a quality of life improvement that lets
It should switch automatically based on navball mode. Orbit is sea level. Surface, radar. Target, distance to target.
The color should change so you can tell instantly which it is now, and you should be able to click it to override it, and click some button to go back to automatic mode.
