How about on the database source include an "Add Menu"
Have it down with the add table, add view, add report and add chart. When you select it this option:
Include under the Menu portion of the screen you would still have "Create menu item for this table" option
AND a second choice of "Link to an URL"
And a third choice of "Create Blank page for editing"
Then you have options for creating pages or putting in information for people to read that might be restricted at different levels that are outside of using the database.
Example:
If you selected "Blank page" - you might want to have paypal code on this blank page and have different prices for different levels or such.
The URL choice - would allow you to incorporate other pages you create outside phprunner you can have links show up in one menu system.
This would be a great addition to the program.
