When creating a new post I would like to add another option. It would be very similar to the option "tags” already existing. As you can enter tags and they will be display under the article, I would like an option "Source" where you can write a line of text (to give the source of the image used on my post). It would display as tags, under the article in a simple and discreet line. The easy way would be to add it directly in the post. I've already tried it but it is not optimal as it conflicts with others changes I'd like to make. I would like to treat it in the code as an independent part (not together with the post) like the title, the category or the tags.
