I really like its format over Dolphin’s, I find it much more intuitive. It shows the whole filetree from root and double clicking a folder just expands the it further. This is different than how Dolphin works, which only shows one folder at once like how Windows does in the main windows of File Explorer.
I think I might be autistic.
Specifically qBittorrent used with Debian and KDE. Not sure of it looks different elsewhere.
You mean the content pane? Dolphin should also have this at Settings → Detail view → Expandable folders, though I don’t know if what I’m looking at is old. I don’t have a KDE system handy.
