Good point, but I use treeview on Atom for 1) creating new files or folders, 2) moving files around, 3) get a glimpse of the current state of working dir in git (Atom’s git integration is awesome). I think I’m not good enough at doing these things on either Vim or Emacs 
I’m currently trying not to depend on treeviews that much and instead embrace the power of ctrlp.
It’s both Cmd+T and Cmd+P here on OSX, I suppose it’s the same too on Windows and LInux.
