If you stay on some inner page, you can see that the link to the frontpage is called 'Homepage' by default.
In order to change it to some other word, you need to do the following:
1. Go to Unyson section in your admin dashboard.
2. Find 'Breadcrumbs' extension and click on the Settings link in it.
3. Type desired text in the 'Text for Homepage' field. And save changes.
