From what I can tell this note was created in 2011, TWELVE (12) years ago.
I saw an earlier reply that asked us to put our responses here as they take our suggestions/feedback seriously.
So all I can say is after 12 years, users are STILL UNABLE TO CHOSE THE IMAGE TO USE ON THE THUMBNAIL?! REALLY?!
I would appreciate hearing from EN on why this has not be resolved after 12 years?
