Allow the hiding of embedded images, animated gifs, videos - like Slack does
Users can paste/embed large, wild, distracting images, animated gifs, videos, etc, into the conversation window. That is fine, but recipients and senders should be able to later HIDE those, because they're ever-present and very distracting--until the conversation progresses long enough that the distracting images get scrolled out of view.
Slack allows these to be hidden and it's a very nice feature.
Updating these items after merging into our main issue. This feature has been completed. Thank you.
