It seems as though this should be as simple as "saving as default" except that option doesn't seem to be available.
I am looking to do two things here:
1. Viewing -- When I open a PDF I want it to display as page panel and page, two-up facing, and fit page.
2. Saving -- I'd like to be able to add a couple toolbar buttons to save the Properties>Initial View setting to a couple different set of values.
I've searched this forum and must be using incorrect search terms because I'm not finding a way to do this.
2 - There is no JSAPI access to the initial view settings for a file. You can add a document-level script to change them after the file opens (which is unreliable), or use batch processing or Actions in Acrobat Pro to apply a chosen view type, but a scripted button* can't write the PDF "/view" tag in the same way Acrobat does when you use the properties dialog.
*Although there are many discussions of scripted buttons on this site we do not have a complete worked example, as it's not nearly as simple to accomplish as the other methods such as adding menu items. Also in Acrobat X there is no ability to target the toolbar directly, instead the user must manually add the button from the bottom of the Tools Pane.
The simplest method given you have Acrobat X is to create a new one-step Action.
File - Action Wizard - Create New
Start with A File Open in Acrobat
Add step - Document Processing / Set Open Options
Click the "options" icon and set the view state to apply
Choose your save option
Save the Action
