1. Profiles & Typography
Settings under this section are profile-bound. Changes apply to the currently active profile (e.g., Desktop, Mobile, Tablet, E-Reader, or your custom profile).
- Active Profile: Switch between built-in hardware profiles or custom profiles.
- Font Family: Select the default Japanese font. Pre-configured for high-quality CJK fonts like Noto Serif JP, Noto Sans JP, and Shippori Mincho.
- Font Size: Base reading font size in pixels (10px–48px). Defaults: Mobile 17px, Desktop 20px, E-Reader 20px, Tablet 22px.
- Line Height: Spacing multiplier between lines of Japanese text (1.0x–2.5x). Defaults: Mobile 1.55x, Desktop 1.65x, Tablet 1.70x, E-Reader 1.60x.
- Letter Spacing: Additional tracking space between individual characters (in rem).
- Font Weight: Typography stroke weight (100–900). Default is 400 (regular) for LCD devices and 500 (medium) for E-Reader to improve contrast on reflective E-Ink Carta screens.
- Vertical Font Kerning (
vkrn): Enables OpenTypevkrnfont kerning tables. Automatically tightens Japanese punctuation (「」,、,。) in vertical reading mode. - Writing Mode: Toggle between Vertical (
vertical-rl) (traditional Japanese right-to-left columns) and Horizontal (horizontal-tb). - Columns: Number of columns per screen page in paginated mode.
0= Auto (columns adjust based on screen width),1= Single column,2= Dual columns. - Margins (First Dimension / Second Dimension): Outer padding around the reading canvas in pixels.
- Max Dimension (Second Dimension): Caps column height (or line width in horizontal mode). Set to 900px on Tablet to maintain traditional bunkobon paperback line lengths.
2. Interaction & Gestures
- Page Turn Buttons: Display on-screen previous/next page chevron buttons.
- Tap-to-Turn Edge Zones: Tap the left or right edges of the screen to advance or rewind pages.
- Swipe Threshold: Distance in pixels required to register a page-turn swipe gesture (15px for responsive LCDs, 20px for low-refresh E-Ink panels).
- Keep Screen Awake (Wake Lock): Prevents the device screen from dimming or locking while a book is open.
- Fullscreen Mode: Automatically enters browser fullscreen when opening the reader.
3. Layout & Pagination
- Layout Mode:
- Paginated: Discrete page flips with snap boundaries.
- Continuous: Smooth scrolling layout (ideal for web novels).
- Wheel Page Flip Lock: Prevents accidentally flipping pages when moving the mouse scroll wheel.
- Custom Anchor Dragging Pause: Automatically pauses reading statistics while adjusting the reading baseline anchor.
- Confirm on Tab Close: Prompts for confirmation when closing or refreshing the tab if unsaved changes exist.
4. Checkpoints & Autosave
- Disable Auto-Save Sync: Prevents local autosave updates from immediately syncing to Google Drive or OneDrive. Checkpoints remain safely recorded on your device.
- Rolling Position Checkpoints: Records rolling position snapshots so you can undo accidental jumps or fast scrolls.
- Checkpoint Interval: Seconds stopped on a page without scrolling before saving a rolling checkpoint (1–30s).
- Maximum Stored Checkpoints: Number of rolling autosaves to keep in memory before pruning older entries (2–20).

12,450 / 84,200). - Overall Progress Percentage: Shows total book completion percentage (e.g.
15%). - Chapter Characters Read: Shows characters read within the current section or chapter.
