Currently, I'm using the "exclude=" parameter to exclude certain pages from my main menu.
But it's tedious having to go into my code each time I want to exclude a page.
The perfect solution would be to have an option on page creation, where I can choose if a page should be visible or not in page listings (menus).
So my questions are:
1. Changing core functionality in WP is never a good idea, and it's always lost anyway when I upgrade. So how could I implement such a feature?
2. Has the wordpress team any plans on installing such a feature?
