High-fidelity LinkedIn preview

From a user:

I'd love an 'above the fold' preview of what the truncated post would look like on linkedin. It's the only reason I use and pay for AuthoredUp and I'd love to switch off of it and only use typefully

My use case is I repurpose everything from twitter to linkedin. I draft everything in typefully because the tweet format helps me write things more concisely, and then i just paste it into authored up to tweak it for linkedin before posting both

It would also be great if this offered a mobile preview as well.
