In Inkscape, I have found the “Extensions -> TeXmacs equation” plugin quite useful in the past.
I noticed in a Debian 10 VM with TeXmacs 2.1.1 installed via the ‘apt’ repository and Inkscape 0.92 (from when Debian 10 was
stable) that the extension no longer works correctly (running “TeXmacs equation” opens two TeXmacs windows instead of one; see screenshot).
I wanted to see how many others noticed this problem and if its worth writing a bug report. My immediate use case is to modify SVG files of figures generated by GNU Octave so I can typeset the axes titles.
