hye,just want to know how to add more custom menu?

Yes, sure!

I also want to know how to add new pages for my own content.

Yes.. can it be done?

I create a module.. But it's totally eat your time. You need to edit the code manually to name it..

This module i created last week and it's for custom "Help Desk" page. You may customize it to match your need.
