In the comments in any airtable record it would be good to have attachment option so users can post pics, videos, files, leave an audio message, video message, etc.
That's a great idea. Attachments like images and videos are indeed a valuable tool when communicating with others, especially when we aim to explain certain concepts—just like the very video you've provided here. I think I might be able to develop a temporary solution until this is implemented natively, assuming enough users are interested in it. Let me know, guys!
