Feature Suggestions – New Shortcode, URL Localization

1) Could there be a new shortcode that could be used e.g. at the end of a post linking the next article in the series? Could look like:

Read next: How to make a movie with iPhone, part 2.

If there is no next article, it would not display anything.

2) Could there be a setting to set something different instead of “series” in the series page URL? In my language, we do not use the word “series” so it is weird to have it in URL.

Thank you so much for considering this.
