Basic components Y U no there no more?

[Chaospepsi]

So, I've played a lot of voltz and UE mods in the past, I made the jump to Bigdig recently and prefer it. I know Bigdig has basic components as there's batteries and cable, but why hasn't it got it's own creative tab? I am aware that recently Calclavia updated BC so it was built into other mods, but even still, by itself shouldn't there be a way to find the items?
