Prepare your course files in a directory structure
Browse your library from the main page, or enter a path manually in Settings
Click a course to load it - folders drill down, courses open directly
Start learning! Progress, notes, and completion are all saved automatically
Not sure what to watch? 🎲 Surprise Me at the top of the dashboard picks a random course you haven't finished

Space - play/pause
← / → - seek back/forward 10 seconds
↑ / ↓ - volume up/down
N - jump into the quick-capture note box (pauses the video)
Drag the video's bottom-right corner to resize it, and pick a default playback speed in Settings - both are remembered
Reopening a lesson resumes from where you left off, and the ▶ Resume button at the top of a loaded course jumps straight back to the last lesson you had open
The Lessons in this section list under the player jumps between other lessons in the same folder without leaving the page

Every note is stamped with the video's timestamp when you save it - click a timestamp to jump straight to that moment
Press N anywhere on a lesson page to capture one without reaching for the mouse
Edit or delete any note from the floating panel at the bottom of the lesson page
Notes (in the footer) collects every note across your whole library in one searchable list
Download Study Guide on a loaded course exports every note as one markdown file, organized by section
If you use Outline, pick a topic on a lesson's notes to push them there automatically when you navigate away

Search courses by name from the Library browser on the main page
Check Also search transcripts to search inside subtitle files (.srt/.vtt) too, if your courses have them
Switch between list and grid (poster) view with the toggle next to the search box - handy for browsing a folder with lots of courses by thumbnail
Hide a course or whole folder from Settings → Manage Library without touching anything on disk
The ☑ button in the Library browser turns on select mode - pick several courses or folders at once to hide or add to Next Up together
Bulk Rename (Settings) finds and replaces text across every course/folder name at once - useful for stripping a release-group suffix off a batch of downloads

Pick a built-in theme or set a custom accent color, corner style, and card style
Adjust font, text size, page width, and spacing density
Set the default library folder, and use Refresh Library if you've just added or removed files directly on disk and don't want to wait for it to notice
Download Backup exports your settings, hidden-path choices, recently-viewed history, and every course's progress/notes as a zip - not the course files themselves
