There are actually many areas in linux desktop that are hacky and unfinished, but this is not one of them. It would be helpful to have that feature, yes, but I never missed it, mostly because of shortcuts in thunar
strg + 1 normal thumbnail view
strg + 2 detailed list.
I see it as very basic feature for a modern desktop/window manager.
So I prefer thunar over windows file manager, or worse, the filemanager on my chromebook any day. So it is very polished software for my use case, even though not perfect.
