When you click on an episode so that you can do a manual search; the plot of the episode you are about to do the search for is displayed in the pane.
Sometimes the displayed plot gives away too much information.
Within Kodi there is an option to hide the plot of unwatched episodes. I believe it would be useful within the Sonarr GUI if you could also tell it to hide the plot too. It might be useful to be able to toggle it on and off but generally; I would rather not see it.
