I 100% agree with the suggestion in the OP - it's easy to glance away for a second and miss the star class in the info screen. They could swap out the current galactic sector text for star class, it'd be a lot more useful and wouldn't require reformatting the box. It makes a lot more sense for the "changing galactic sectors" to show up in the info panel, IMO, since it happens so infrequently. Yes, you can see you've got something dangerous coming up (Neutron, WD) and get a sense of star class in the Witchspace loading screen, and yes, you can check the galmap, but it sure would be a nice QoL improvement. It's annoying that it goes away in the info screen the way it currently is.
Something like:
STAR CLASS G (SCOOPABLE)
-------------------------------------------
SOL 20.54 LY
--------------------------------------------
HIGH SECURITY
CLEAN
