Add "Display Author", "Link to Author Page", and "Display Categories" settings

[KZeni]

I've updated the widget, form, and display function to allow for displaying the author's name with it optionally linking to the author's page (both are settings).

Just added another setting which allows you to output the categories for a post.

Nice, I used your code to display tag, I used "get_the_tag_list();"

Do you think it's possible to display a thumbnail for a specific tag.
ex: display the thumb 1.jpg for the tag with the id 1

Best Regards

@BenTen Seems like you might want to use https://wordpress.org/plugins/quick-featured-images/ to automatically apply the desired featured image(s) based on the tag(s) being used. This will then have that image be used as the featured image for any/all spots on the site which looks for the featured image (RPWE, included).

However, if you want it the tag thumbnail to be the actual featured image while still showing an image based on the tag... it might be better to write your own shortcode for accommodating displaying things exactly how you want instead of relying on RPWE to do something it really wasn't built for (some extensive modifications would need to be made & probably won't be worth it if it isn't adopted in a future update of the plugin.) That said, I don't see why you couldn't make this update and propose it as a new pull request to add the functionality for yourself & others moving forward.
