Hi again,

now i found out how to get the footnote-number:

local num = current.numberdata
local test = num.numbers
local num = tostring(test[1])

but i also found out, that my plan of iterating through the notes was
indeed senseless, because at this stage the next footnote is not known.
(i should have tested that first).
So my new plan is, to calculate the correct width in
everybeforenoteinsert, and to compare it with the first one of the page.
My question now: is there any possibility to restart the page when i
find that i need a greater width?
eg to invoke a command \justdoitagainsam??

Sorry that i make so much noise about such a silly footnote-thing, but
all my books have many footnotes, and all the notes have to be
typesetted like that (not my idea)
So without, i could hardly use ConTeXt anyway and that would be sad...

Greetings,
Achim
