1. Only one listing can be open at a time.
2. Expands listings out a bit and animates them.

Listing expand animation is slightly jerky. You've probably already looked into this but: mui/material-ui#3241 features some discussion on animating expansion of Cards.
Also: mui/material-ui#3392

It's an improvement on our existing animation (or lack thereof)--if you feel strongly about the animation, I recommend opening an issue for the future.
