Okay, I've included it in version 4.0.4.
I also happened to notice the work you've done on Black Rubber Belts - Remastered. It only now occurred to me that the Express transport belts in this mod (the blue ones) move 60 items/s, and you double-spaced the arrows like Turbo transport belts in Space Age.
So I figured I would follow suit and double-space the standard texture.
