I use page-links-to in all my WP websites. I consider it an essential part of every installation but there is one thing it doesn't do that I think would be a very valuable and useful addition. adding an option that removes the default WP page link.
Imagine the situation where a particular page is a parent with several child pages. Using a plugin such as Multilevel Navigation, the parent page appears as a main menu item and the child pages within a dropdown menu below the parent. There are many times when i want the parent item to not link to a page so that when the user hovers over it, he can't click it to go to another page but must choose from the dropdown menu choices.
I have seen many people searching for such a solution, including myself, and not finding one.
