Can we have a test/sandbox area to try things out before going live with a page. I have made a test page but to see it I have to make it Active. I can password protect it; but, anyone with the password for other pages can get into it. Or...I have to test things late at night and hope no one is online. A test/sandbox page would be awesome. Thanks.

Here's how you can accomplish this now:

1) Activate a blank Customizable Page
2) View the page live and bookmark it
3) Now deactivate it. Add whatever content you want to the page
4) Use your bookmark to view the page. It's there, it's just not on your left navigation.

All Customizable Pages of your site are actually there at all times. Having them deactivated simply removes the link from your left nav and makes it impossible for anyone to get to them. It also makes it impossible for search engines to spider the page too. But as long as you've previously copied or bookmarked the link, you can view the page even though nobody else can get to it.
