Collapsible images and link previews
Add a collapse button for images and link previews for those times when someone posts a massive animated gif into the channel.

This feature has been completed and is available in v4.4 which shipped November 16th.

Hey Taylor, there is this help wanted ticket up for grabs that would resolve your issue. Is anyone interested in working on it?

Thank you for adding this feature, the problem I see is that after I change channels and then return, all the link previews are uncollapsed. This is happening in our Town Square channel.
