I'm by no means a programmer or something like that. So, I need further instructions.
1. Do I have to substitute 'tweaks.tweaksSettings()' by 'tweaks=tweaksSettings()'?
2. Which one could be the "real command" that I have to put at the place of "some shell command \"?
You are right: when I re-opened the .ini-file, my impression was as if the plugin had substituted my entries by some other ones.
Meanwhile, I have been playing a little, and I saved the file in "Kobotweaks"; now my insertions stay there (more or less), but the result was the same as after the first installation of the plugin.
I save the file in notepad++, but directly in the .kobo file of the reader. Is this a wrong procedure?
Sorry for my ignorance! thanks for your help anyway!
