This one is for the beginners. Quite some time ago, Blogger introduced the concept of Static Pages, where you can create up to 10 stand-alone independent pages. To add the links of the pages to your homepage, Blogger came up Pages gadget. Pages gadget is a cool add-on. It sits below the header and serves like a menu bar or navigation bar to your blog. But here comes the down-side: you can't just add any links to your bar (at least not easily). You can only add your static pages' links. In this pictorial walkthrough, I'm gonna show you how you can use LinkList gadget as an alternative to Pages gadget to make your very own customized navigation bar.
Beginners ignore this: For those of you who are looking for ways to dissect and edit your Pages gadget instead of switching to Linklist gadget, you can refer to this post.
Update Note: You can readily add external links in Pages gadget using the new Blogger interface. Do give it a try.
That will be all folks. Cheers and God bless.
