Hi,
I have for some hours tried to understand how to work with
     columnsetspans (I'm trying with an updated lmtx), and have some
     questions.
1) Is it only the floats that has the long list of placement

"default=fxtb:2*10" and similar options for other elements than
     floats). It would be useful to have it for other type of elements

2) What is the current correct way to get back on grid after

The only key that had lead me to something that seems to work in
     \setupformulas is "option=depth". Is that the way to go?
3) This is a bit unrelated, but is it possible to set page
backgrounds

on specific page. Something like \setupbackgrounds[page][page=3,
...]
...
(I cannot find any keys for this in setup-en.pdf). Right now I
can set

it for an odd and an even page, but then if I want a background
on the

page after that, I have to put that code at the place where it
will be

used. (I got an error with \startpostponing[+1] ...
\stoppostponing)

4) To be a bit more concrete on the first issue: In the example

how can I place the columnsetspan at the bottom right? Second and

Hi!
I have looked more carefully at the columnsets manual, and it looks
...
...
...
(parts of) the columnsets mechanism is somehow broken at the moment,
since some of the examples there are not showing what they are
supposed to.
the mkii mechanism has been replaced by a new one but it's not
completely compatible (these placements are actually for floats and
spans were just a special kind abusing that mechanism)
...
Can this be confirmed? Is there a plan to get it to work soon again?
i'll put it on the todo list

Hi!
Many thanks for your reply! Then I stop my playing with it now
(several things work and it looks quite nice!).
I really appreciate any effort in this direction, since I think this
grid+column functionality is a very nice feature to have!!

Many thanks for the update today!

One follow-up question: How do I place a columnsetspan on a right page in a
spread? If I change c=2 to c=4 in your example, it disappears. Is there
another way?

I have realized that one can use columnsetareas to "forbid" text to go to
certain lines, which is useful. But I have the same problem with them, not
showing up on right pages if I use x=4 (for example). This is perhaps not
the intended way to use areas, but it works pretty good on left pages to
have the columns start on other lines than number one, or to make them stop
before the last line, so it would be fun to have them on right pages as
well.
