@cos @libreoffice When loading a non-native file format, LibO translate it into its own internal representation, you never really work on the non-native format, you always import/export it, which means that after a few rounds you can get a messy file. On any program, it's always better to work with the native format. Also, using Writer to write a markup file is like using a sledgehammer to crack a nut π Better use a lean, quick markup editor and only at the end import it for the final touches.
