I see no point in arbitrary restrictions.
That was mainly what I was wondering about in the first place.
Shouldn't footprints be something like functions in programming? Or
maybe slightly more similar to macros?
There is one caveat, though:
Layouts can contain layers
Layers in the footprint have to be mapped according to the principle
of least surprise.
Last we talked of this, I mentioned symbolic layer tags vs physical
layer tags. So footprints would have top/inner/bottom layers, boards
would have 1(top)/2/3/4(bottom) layers.
Yes, mapping everything is

We talked about that. It's hard to do but not impossible :-)

This sounds like recursive call of footprints to me
No. In this scenario, the footprints do not contain real, editable
text. What looks like text to humans is just

It is irreversible, meaning, the text cannot be edited after the fact.
I think I got you now: you want to place one footprint per character or
generate a footprint,
that displays your text -

I'm somewhat confused about the workings of PCB in this aspect - I
suspect this has something to do with the complexity of rotation etc.
Polygons are (usualy) defined by their corner points. Rotations of
points are
most often done by multiplying with a rotation matrix

If the text in footprints should behave like any other text, I'd
say pretty hard. You'd have to adapt many places where footprints
get rendered.

Each time I try to add text to an element, it just disappears. I

Hello all.
I seem to remember I read about this a time ago, but me and google can't
seem to find any reference:

connector on the silk screen), but that doesn't seem possible... Each
time I try to add text to an element, it
The current Element syntax doesn't allow for extra text in it, sorry.
