Visual indicator of changing situation Atmosphere/Space High/Low when orbiting a planet

When orbiting a celestial body, I would like to have a (vanilla/stock if possible) visual indicator of the transition of the position of my ship between altitude situations. In KSP there are several situations :

• Landed / Splashed
• Atmosphere Low / High
• In space Low / High

I know that a device is capable of showing in which biome I am but I want this position.

I also know that the wiki has this information but I would avoid doing alt-tab because I have the mouse on the "take measure" button and the transition may be quick...

I noticed several visual transitions :

• Landed / Splashed <-> Atmosphere or space : obvious
• Space Low -> Atmosphere High : music stops, wind sounds and atmosphere meter moving
• Atmosphere High -> Space Low : atmosphere meter at top left, Ap stops moving and music starts
• I noticed that sometimes the camera moves to another angle while descending

Visual indicators of Atmosphere Low <-> High and Space Low <-> High could help. Did you notice anything when transitionning these states ?

Kerbal Engineer Redux is your most likely option. It provides tons upon tons of information not normally available, but you can switch it all off. In flight you normally get two HUD panels displaying several lines of data each. You can customize these too, and leave only 'situation'.

It's not perfect though - e.g. it doesn't recognize the microbiomes of KSP. Whether you're at VAB, launchpad, runway, you'll always be 'landed at Kerbin shores'.
