Key Features

Dual-Mode Artist Shading Engine

• Black & White Mode (B / G): Preserves full 256-level smooth grayscale gradients and subtle tonal transitions for painting studies.
• Value Mode (T): Stepped posterization that isolates hard terminator lines, core shadow shapes, and lighting planes for fast form breakdowns.

Vector Redline & Annotation Suite

• Draw directly over your references with responsive vector ink (D).
• Full Undo / Redo stroke history (Ctrl+Z / Ctrl+Y) and a dedicated Eraser tool (E).
• Multi-Format Clipboard Export: Copy redlines (Ctrl+Shift+C) and paste them directly into Clip Studio Paint, Photoshop, or Discord as transparent 32-bit PNG graphics.

Manhwa & Webtoon Continuous Vertical Mode (M)(Still has some Problems.)

• Seamless vertical strip reading with hands-free auto-scrolling (Space).
• Windows Natural Sorting (StrCmpLogicalW): Panels and chapters sort chronologically in human order (1, 2, 3 ... 10, 100) rather than alphabetical order.
• Customizable strip width presets (700px – 1600px), scroll speeds, and panel gap spacing.

Detail Loupe & Advanced Study Filters

• Floating Inset Loupe (Z / Alt+Z): Inspect fine brushwork, facial features, and anatomy up close without losing overall canvas perspective.
• Adaptive Sharpening (F) and Line Art / Sketch Extraction (L).
• Zero-Repeat Shuffle Bag: Guarantees you cycle through every image in your folder before any reference repeats.
• Universal Library Auto-Discovery: Seamlessly links and shares existing reference folders across all drives without duplicating files.
