Thanks! I understand more about you want now.
Well as you can see, the preview excerpt text is already included (whether or not you have images)
You are proposing having thumbnails auto-generated to depict the text of the conversation including elements of the interface.
That would currently be a duplication of sorts?
I’m not a great fan of text as images, but that’s me.
But for sure, maybe we could have that added as an option?
