Would it be possible to add a mode where one type of concrete is placed in the construction area, and another type is placed in the logistics area of a roboport? Mainly so it's easier to spot where you can stand to receive supplies.

Ooooh. That's absolutely do-able. I'll need to think about /how/ to do it, but I definitely can. Adding a note to my github project about it.

I just released a version with a basic version of this feature, if you want to check it out.

Ayooo

Found a tiny bug: The refined concrete will place one tile too far on the bottom and right sides of a roboport's construction radius.

Hmm, I'll see what I can do. Probably just a small quirk of the math, because of how the coordinates of tiles work.

Okay, found and fixed. Thanks again!

of course!
