Am I missing something or were we able to add text to either the left or right side when using sidecar in beta? Like in World Heritage in Danger. Will this feature be coming back? It really helped to break up monotony.
I also liked how the title card in The World's Top Destination Cities is set up like a sidecar instead of just a title and summary. Just some observations.
*Edit*
I just realized the cover layout can be changed using the design panel.
