matteocontrini I just tested this at my forum. If you copy an image from the web, it doesn't store it as base64, it grabs the image's url. Which is actually a really nice feature. After copying and pasting an image, then looking at the code view, it's:
![Numberblocks games: 5 active ways to learn maths | 5 Minute Fun](https://www.5minutefun.com/wp-content/uploads/2017/10/2310_numberblocks_873_446.png)
It makes it that much faster to insert an image which converts to markdown.
But, I do see the negative side... conflicting with other extensions. Although, the first post says it will work with fof/upload which I know includes drag and drop. So, if there's a conflict maybe it's solvable.
