This is about functionality, not looking pretty. They spent a bunch of time on making it look modern which IMO was not necessary. But they spent no time on making the thumbnails function the way that any normal person would think they should if you asked them.
I get that a lot of people probably use list view so they don't care, so maybe this isn't a popular request. But for those that want it, it's a big deal. There is no software that comes close to EN for what I need it for, so I'm likely not going anywhere, but it is one of the few things about EN that grinds my gears.
