Ah, I see. It's ok, it's not that big of a deal for me, I was just curious.
1. Agree, it makes sense that they show up there, mainly because no one uses them in the early game, they are only really useful for cooling nukes and ISRUs.
2. I don't know about this one, enhanced suitability is a bit too early for the larger heatshields and chutes.
3. Agree.
I think Unmanned Before Manned makes those changes, so you could check it out.
If you don't want to install that mod, and feel brave enough, create a .cfg file with the following:
@PART[landerCabinSmall]:NEEDS[CommunityTechTree]
{
@TechRequired = simpleCommandModules
}
@PART[radPanelSm|radPanelLg|radPanelEdge|foldingRadSmall]:NEEDS[CommunityTechTree]
{
@TechRequired = heatManagementSystems
}
@PART[foldingRadMed|foldingRadLarge]:NEEDS[CommunityTechTree]
{
@TechRequired = advHeatManagement
}
And put it in the CommunityTechTree folder. You can edit, remove or add more parts to whatever tech node you want, as long as you keep this format.
Hope it helps
