Last time I checked, Loqseq didn't support free-form text / Markdown as it's an outliner (only). Now I recently heard[0] that there's a "temporary free-form text mode" now(?) – I have yet to check it out but going by what people have been saying on the internet until a few days ago[1,2,3] this doesn't seem to be solving the problem or otherwise people would have stopped complaining.
