After some experiments with ftcolumnflow, I have some observations and a recommendation.
I have a github project implementing markup for scientific paper writing. For this project,
a principle value of this ftcolumnflow is an ability to print documents reliably on 8.5"x11" paper.
Multi-column multi-page flow is very valuable, and you have done a great job of achieving this.
One remaining challenge is to output a page break just before horizontal red outlines after the first.
I would like your help.

I have spent a couple of days experimenting with page sizes and modifications to your code.
In Chrome Browser 1090x1470 is close, but the red boundary creeps up to the previous page
from being on the next page by page 34 of print preview. In Safari, 1090x1468 had no creep
by page 129. Experiments with Firefox were incomplete so far.

Some code modifications I tried included CSS page-break-before, but those all fail because
You ingest the text hidden and rewrite it into your cf-pages. Beautiful, but refractory to breaks.
I am happy to adjust the size of the red outline, but during my experiments I found that
sometimes the text overlaps the outline.

Is there any advice you can give me? I will continue experimenting.
