Content Browser

The Content Browser at /content is your central place to find, download and start lesson sets. It is built around the learning flow: search first, then Continue Learning, then the catalog.

At the very top there is a full-width search field. It filters instantly (debounced, against the locally cached catalog) across set titles, descriptions, domain, lesson titles, card fronts and backs, and tags. The search is tolerant of case and accents and understands German digraphs (ae/oe/ue/ss). Matches replace the catalog tree, with highlighting, a match count and an empty state. Cmd/Ctrl + K jumps straight into the search field.

Continue Learning

Right below the search, Continue Learning shows the most recently touched lesson per set, each with exactly one action: resume (in-progress/paused lesson, step n of total), next lesson plus stars after a completion, or set complete.

Languages and Knowledge

The catalog splits into two trees:

  • Languages — as a tree source language → target language → level, filtered to your app language (you can enable additional source languages in Settings → Learning).
  • Knowledge — non-language domains (e.g. programming, psychology) with their own icons.

Source badges and source filter

Every downloaded set carries a source badge that shows where it came from:

  • Official / Bundled — from the official catalog or built into the app.
  • Own repo — from a repository you connected yourself.
  • Officially recommended — from the curated recommendation list.

A source filter lets you show only sets from a specific source when needed. More on this under Multiple content repositories.

Book recommendations

If the catalog maintains recommended books for a domain (books.yaml), the Content Browser shows them as further reading for that domain. This works in both storage modes and needs no backend. Format and maintenance: Book recommendations.

Subject filter

If you have assigned subjects to your learning projects, the Dashboard shows a subject filter that lists only your own subjects (hidden when there are none), sorted by most-used first and grouped by category above five entries.

My Lessons

Lessons you created or imported yourself appear in the My Lessons section with actions to play, edit, delete, export and share. How to build your own lessons is described under Creating lessons.
