I'm working a lot right now in
All Documents view, but am frustrated with wanting to hit one icon, like windows explorer or all browsers have to go back 'up the chain'.
Is there a way to enable this for my SharePoint site?
I'm not sure I understand exactly wht you want but here it goes. In SP 2007, you have the site level breadcrumbs which allow you to go "up the chain" at the folder / list level all the way up to the current site. You also have the global breadcrumbs at the top that allow you to go "up the chain" to parent sites in the current site collection.
