Q: Is there a setting so that when I open a document that the default setting is to show the thumbnail picture of each page on the left hand side. Currently, each time I open a document, I need to click on the “page” icon on the left.
A: Yes, if you go to Preferences -> Display you will find the setting to set the Navigation Tab.
If you set this to “Pages Panel” this will always show the page thumbnails when documents are opened.
