Enable or Disable the “Start” Workspace?

This is also in the Preferences dialog. Just go to InDesign (PC: Edit) > Preferences > General, and the option to Show “Start” Workspace When No Documents Are Open is right there at the top—check or uncheck as you wish. Just in case you aren’t sure what this actually is, let me offer a quick explanation. When you open up InDesign without a document open, you’ll get a start screen showing files you’ve recently opened, giving you a quick shortcut to open them again. With Show “Start” Workspace switched off, you’ll just see the standard InDesign workspace, and you can go ahead and fire up a new document or go to File > Open to open the document you wish to continue working on.
