Added Breadcrumb Links to the site (look above the page Title)…
Thinking of rolling this up into a Theme Component for Discourse…
This is slightly redundant with clicking on the existing category and tag buttons (or are they links) under the Topic title, but in my experience, that feature is mostly unknown to users without explicitly telling them.
A different way to implement these breadcrumbs could be to relocate those to just under the header and re-theme to override the square icons.
