ah thanks, it never worked when I tried it, so I thought it was broken. But apparently my SU has some trouble making correct faces with FAK and complex curves and precise helixes. Got it working now though, so thx .

Well I do need some kind of scaling. As you can see from the image, I'm trying to make a spiraling tower. I need to make windows in the vertical segments, but the tower is quite large and the vertical segments get smaller as the tower gets higher. So I need the windows to follow the spiraling path upwards AND have them scaled down according to the height. Then I'm going to subtract them from the vertical segments to create the arched openings. It's a total headache

What would be the best way to let it "grow along path"?

haha, yes, unfortunately 1001bit lacks a feature that FollowMeAndKeep does have, it doesn't lock the z orientation. So basically both of them lacks an essential feature of the other... and I don't know a way to combine them .

I like this tool, but it is lacking a basic feature that 1001bit's version does have: a reference point.

FollowMeAndKeep automatically uses the center of the face that it wants to extrude as the reference point for the path. When using a more complex face that needs to be extruded along a path relative to let's say the bottom left corner, you're out of luck
