I noticed that too and already had made a new updated version of the Dark_Crew_Screen2 Mod version 2 to include also a red repair wrench.
It is sitting over at Terrapin's website or download from the thread link about a month ago. It contains the extra tga in red.

It is nice to see you thought the same as I did.

Small update that adds an easy to see red small wrench icon in the repair screen.
