Oh, many thanks! In a previous life I did CSS for a living, so it feels
a lot more familiar than Guile... Still stuck on where to put the cwo-
invoice.eguile.scm file though! I purged GnuCash, deleted all *gnucash
folders, and installed v3.10 which I found in my distro's backports
(Devuan Beowulf). Can't get to 4.0 without a manual install, and I much
prefer to stick with distro maintained packages, unless it is
absolutely necessary. Way I see it that's what the distro repos are
for, and I always have automatic updates enabled. Trust, security and
ease of maintenance are important to me. I might consider using a
GnuCash apt source to install from if one was available - you seem like
a thorough and trustworthy bunch. 
But yeah, where should I put cwo-invoice.eguile.scm?

made me more confused! And how do I apply the .patch files you so
kindly provided? I would prefer keeping everything under my home dir,
for ease of backup...
