@geddi Thank you for the kind offer to translate this plugin. I need to do more to prepare the plugin for internationalization, and I will aim to do that in the next version. However, in the meantime, I can send you the POT file if you would like to email me at firstname.lastname@example.org.
The option to glue the slider to the mouse pointer is not available in the plugin yet, but I can add it to a future version. I will keep this in mind for an update this year.
