how to prevent tree-view left pane when opening a single file?

[ijl20]

I find I most often do not need the left-pane tree view open. Atom is my editor-of-choice so it's configured to launch when I inspect many file types by clicking in the OS (Linux, Windows) file explorer. So I find my most common file-open sequence has become:

1. click file to view/edit in Atom
2. close the empty left pane tree view.

After maybe 2 years of Atom (it's better than VS Code IMHO) I've discovered I can 'disable' the tree-view package and this gives me the default behaviour I need without breaking the editor. The ftp-remote-edit package (which I use a LOT and is a particular reason to like Atom over VS Code) displays its own tree view without using the tree-view package, so that is an unexpected major plus given my drastic hack to stop the tree-view pane appearing by default. E.g. "atom .bashrc" gives:

I don't dislike the tree-view package, and disabling it seems way too drastic.

Is there a way to NOT have the tree-view pane appearing by default when I open a file.

Into this file:
~/.atom/init.coffee
Add this code:

atom.workspace.onDidOpen ({item}) ->
  itemName = item.constructor.name
  if (itemName  != 'TreeView') # no action if open TreeView intentionally
    dock = atom.workspace.paneContainerForURI('atom://tree-view')
    if dock && dock.isVisible()
      dock.hide()

:O that doesn't seem too hacky, either
