Icon always displays (even when no categories to display) & unlinked

First, thanks for creating this module. I like breadcrumbs, and this plugin is easy enough to use.

I have two things about this module that would improve it.

1. The icon (say for the home icon) always displays, even if no category is present/listed. So on the home page, the small home icon I have selected always displays.
2. This same icon is not linked. Would be useful if it was linked along with the HOME text (or whatever is specified by the user in the plugin), and would therefore also change color to match the link color specified in the site.

The page I need help with: [log in to see the link]
