Hi,
I uploaded a new lmtx version. This time a new mechanism.
This is very interesting...I haven't played around with it, but is it the case that \markanchor does not do alignment and so can completely replace the old \hpos{...} class of macros?
This also gives many interesting possibilities for math .... drawing "boxes" in matrices (e.g., https://tex.stackexchange.com/questions/333011/draw-a-box-around-matrix-elem...) or even the nath style `\wall` macro (see pg 11 of https://texdoc.org/serve/nathguide.pdf/0) ... Of course, I mean this in terms of the visual effect and not the interface. Like this ... I'll think about taking some size into account (a bit like hpos does).
Yes! If we can take size of cell into account, it will be perfect.
We can also think of a wrapper so that an explicit \framed is not needed. new upload with nesxt step
