Hi,

I gave it a quick look, too, it does stuff like

             // Unfortunately this is the only way I've found to close 
the Flatpak
             // version of libreoffice.
             std::string command =
                 R"(kill $( ps -aux | grep -F "/soffice.bin" | grep -F " 
--headless --nolockcheck --norestore --convert-to pdf" | grep -F " 
--outdir"| awk '{ print $2 }'))";
             QProcess process;
             process.setProgram(QStringLiteral("bash"));
             process.setArguments(QStringList() << QStringLiteral("-c") 
<< QString().fromStdString(command.c_str()));


That will just then kill any kind of libreoffice instances or perhaps 
even inject other commands depending what this grep matches.

I tend to agree that this would rather need some major overhaul.

Greetings
Christoph
