How is that different than what exists? Perhaps in that it is applied
post-rotation? That would make it a bit simpler, assuming the offset can be
large enough to place the label anywhere.
I think I could, with a little ugliness, make the current labels work if
the offset could be > 127. Or, I could use absolute scaling, try to figure
out where the screen boundary approximately is in angstroms, and use that
to draw an arrow from an echo to an atom. Anything that would reduce the
ugliness would be good lol.
Thanks,
James
