[NTG-context] margin notes (was: lmtx update)

[Otared Kavian]

Hi Hraban,

Thanks for the hint… indeed I did see that \ColWidth command but didn't think about its definition… Sorry!

Now with \ColWidth defined, your code works fine and it has the advantage that the text of the sidenote begins in the margin at the level where the \footnote command appears. However, it cannot control the overflow of a sidenote to the next page, whereas the code given by Hans can do that. I admit that this does not happen very often since a well designed text should not have too many long sidenotes…

In case other users would like to use your code, I put the whole example below.

Best regards: Otared
%%% sidenotes, or footnotes in the margin
%%% example given by Hraban:
%%% here the tweaking of the width of the sidenote is turned off
%%% remove the comment where there is \ColWidth
%%% in order to adapt to your layout

\def\FNVOffset{0} % Negative vertical offset of footnotes in lines
% Manual tweaking was necessary for a while, when stacking didn’t work reliably.
