If I launch a vessel with multiple sub-probes/relay satellites, I’d like to rename them to Relay 01, Relay 02, Relay 03 etc., or an LKO station has its name from VAB/launch, until something docks to it, then it has a generic name + (combined).
I see/use the ‘pencil’ icon to enter a renaming mode, give it a name, hit Enter/pencil again, and it usually renamed itself for a while, or sometimes you’ll find you’ve just renamed the KSC instead, despite having Focus on your probe/station. Leaving Tracking Station and/or moving to control a vessel usually causes all vessels to revert to their previous names.
I observed this behaviour in Launch version and Patch One (0.1.0.x and 0.1.1.x).
