Copy 'n' Paste paragraph creation

Problem/Motivation

Editors usually do not actually write articles in the CMS, mostly they write them in Word or something similar. When creating the article in thunder, they usually have to cut and paste the different parts into new paragraphs, social embeds paragraphs have to be added, images uploaded and integrated.
it would be much nicer, if the editor could just copy the whole text and paste it into a single import field, which would create all necessary paragraphs automatically.

Proposed resolution

To separate text paragraphs should be relatively easy, embed codes could be automatically extracted, if the url is given e.g.:

This is the text of the first paragraph. The next line contains a pinterest link, this could be automatically transformed into an pinterest media entity and paragraph:
https://twitter.com/zeitonline/status/907918462319808513
(This will be the second text paragraph) Similar behaviour could be used with other embed codes like youtube:

More complicated is the integration of an image, i have no idea yet on how to do this.
