Ability to save (export) parts of a discussion as a plaintext log file
Basically the same wish as what I had filed in https://gitlab.gnome.org/GNOME/fractal/-/issues/165
xchat-gnome had this feature but it was broken (gave me garbled files 9 out of 10 times), Hexchat has this feature (and it works!), and I would need it to consider any new client.
