Now that PDFs previews are done , would be great to have something similar for web URLs. Some differing views on Slack chat. I have selected only the positive comments 
“visual cues for scanning /organizing links” , “rich snippets do a lot for scanning and understanding” “Like Youtube embeds you should be able to switch them on or off and potentially edit/overwrite them.“I do find the icons useful in browser tabs and who knows I might change my mind in workflowy too.” " I think the comparison with pdf previews is good as well. It is really helpful to have more than a title and colored text to quickly grasp what you’re dealing with” “I would be thrilled if URLs pasted into the app were just auto-replaced with the title of the web page of the URL Cards would be cool too! As long as there was some level of customization (ability to choose whether to activate cards for their links or just to keep the original URL)”
