I would like to get a thumbnail of the link I post in the description or comment section, like on Trello or Facebook.
I was thinking the same thing today. I was trying to create an “Idea Board” project and would have loved to be able to see a thumbnail of the article I am sharing.
Having to take a screenshot and post it as an attachment is a little too much work in my opinion 
Also, maybe the possibility of adding a link as an attachment?
