Add option to screenshot a single post

[medeotl]

Describe the request

It would be nice to have an option to get a nice-looking screenshot of a single post.
The rational of this issue is similar to the feature many (all?) GTK's apps have, Tuba included, to get a screenshot of the app via hederbar --> right click --> Take Screenshot.
You can always make a screenshot with the DE tool but it's not a single click behaviour and the result is not optimal.
Use case for this feature request: Find an interesting post and want to share it on social media / whatsapp / mail.
This follows the GNOME HIG, I guess.

Isn't it better to share a link to the post instead of a screenshot? It is accessible, consumes a fraction of the data to send, helps avoid spreading misinformation via fake or doctored screenshots, respects the visibility settings of the original poster, gives credit to the original source etc.

mmm, main reason is that I have no friends with Mastodon account, so they can not interact with the post, and click on a link to get the post is not as immediate as looking at a picture, but I can understand your point of view
