My organization uses design prototypes a lot to work on content and oftentimes I need to be able to share a link to an interactive prototype on the web within a content piece so collaborators can refer to it. Currently, I either add the link in the comments section or the activity feed and it ends up getting lost as the item is worked on.
I would love to be able to add a link as an attachment object and give it a unique title, as shown in this mock up:
A unique graphic on the left would quickly identify it separately from normal documents. Since there's no real need to download the web link as a file, the action item icon would open it in a new tab. Anyone would be able to click on it to go directly to the link and can remove the link just as they would edit a normal attachment.
