I think this may be acomplished with the ability to add a url has homepage. I just tested it with a local file url, and it works perfectly.
However, it would be interesting if the homepage had access to Orion Internals via some sort of syntax. This could be used in conjunction with HTML to populate Orion's bookmarks onto a user-created page
imagine populating bookmarks with something like
<a href={OrionInternals.fectchBookmarks.url(1)}>
<img src={OrionInternals.fetchBookmarks.img(1)} style="width:80; height:80"/>
<p>{OrionInternals.fetchBookmarks.title(1)}/>
</a>
It would be important that only the user's homepage or programable buttons have access to OrionInternals, otherwise untrusted sites could access this data.
