As the subtitle says, if you have TEC mines under construction you can't select the Novalith quickly while zoomed out (by clicking the lower "quarter circle" thing for system defenses.
Not a really big thing, I guess, but it means for the duration of constructing 150 mines you can't select your novalith very easily... so that's like.... 5 minutes? 10 minutes? I dunno.
(anticipates "add it to hotkey" response, followed by my "no")
