ANY GOOD GUIDE FOR CUSTOMIZING THE MENU?

I've poured over 500 hours into my game so far and haven't even touched the menu system yet, but I think I'm at the stage of development in the game where I need to get that nailed down. Does anyone have a link to a guide on how I could go about editing the default menu?

I basically just want to list items, journal, save, and quit since there is no combat in my game. It's a story/adventure game with puzzle solving. So I don't need to display the character portraits and things like that.

I've messed with it a bit, but I really have no clue what I'm doing. Hoping there's a guide out there that covers it.

Thanks all!

Looks really cool, but I was going to learn how to do it myself. Just wondering if anyone can recommend a how-to guide? :)
