Irad Deutsch, 4Z1AC has developed a new mode for HF chat. "VarAC is a FREE, modern HF P2P real-time chatting application for the amateur radio operator that leverages the VARA protocol".  I have not tried this new mode but a demonstration on AmateurLogic.TV on April 15, 2022 looked interesting.

The software download is for windows operating systems only.  https://www.varac-hamradio.com/
