I tend to make the "home" button just do something like
self jumpToPage: (HomePage new).  I've never come across a situation where
I actually needed to jump back to existing instances of pages, and I'm
pretty sure it would be a bad idea anyway (given the way backtracking
works, they might not be in the state you left them in).

As for providing it on each page, you probably want to one of these two

- have your entire application live inside a "frame" component that looks
something like

<h1>Tim's Tremendous Tester</h1>
<page sea:id="mainPane"></page>
<a sea:id="home">Go Home</a>

where mainPane is where the real action takes place.  Or,

- create a "border" component that looks like

<h1>Reading and Riting by Rowledge</h1>
<a sea:id="home">Homewards</a>

and then wrap that around the rest of your components like so:

<page sea:id="border">

I'd recommend the first way, but it's good to know about both.
