I have a small suggestion.

It would be nice to be able to save only representative images by applying meta tags (like Open Graph) of web pages.

For example,
This will include a full image of this web page when you save an article from Cnn.com (https://edition.cnn.com/2018/04/30/asia/trump-kim-summit-dmz/index.html).

However, save the thumbnail of the meta tag's "twitter: image" (https://cdn.cnn.com/cnnnext/dam/assets/180309115432-02-trump-kim-jong-un-split-super-tease.jpg) I think Crop is not necessary and easy to remember.

But for me it's still a nice add-on without it.
Thank you.
