Currently, a user that can only edit static pages, can change the widget settings and be able to edit pages or partials, which they shouldn't be allowed. The widget should be able to check the user permissions when selecting the type of content to edit and/or when saving the changes. Would be great if a site owner could add the widget to users' dashboards and decide which content that user can edit using the widget, without the user being able to change the widget settings.

Thank you for your suggestion! If you like to prevent editors from changing the widget options, use the Backend Elite plugin.
