I’ve just downloaded the trial version of Scrivener. When I opened the Tutorial the left-hand panel was there,but has now disappeared before I have had a chance to try it out.
How do I restore it so I can play with the programme?
If you mean the whole left sidebar with all the document titles is missing, then you probably just accidentally hit the icon button to close the binder and hitting it again will restore it. That’s the leftmost of the main toolbar icons, looking like a three-ring binder. You can also also choose View > Layout > Show Binder.
