Current capabilities

• Single-instrument score mode (Koto, Shamisen, or Shakuhachi)
• 4/4 timing grid with fixed structure:
  • 1 column = 4 measures
  • 1 measure = 4 beats
  • 1 beat = 2 eighth-note slots (with midpoint divider line)
• Drag and drop from instrument-specific palette into any slot
• Drag and move existing symbols slot-to-slot
• Instrument compatibility checks when dropping symbols
• Shamisen palette with string-specific notation sets:
  • Ordered neck-style: all base notes first, then dotted octave notes
  • San no ito: 1..9, then 1•..9•
  • Ni no ito: 一..九, then dotted octave markers
  • Ichi no ito: イ一..イ九, then dotted octave markers
• Shamisen quick marker buttons for selected cell (apply/remove ス, ^, and ♯ in one click)
• Default ornament and sharp controls for newly placed Shamisen notes
• Shamisen rest symbols in their own category: empty circle (○) and circle-with-dot (◉)
• Right-side sheet title follows the score title text
• Column headers show starting measure numbers (1, 5, 9, ...)
• Per-slot 16th-note support by splitting an eighth slot into two stacked mini-slots
• Up to 8 columns rendered per page; additional columns spill to next pages
• Page navigation controls (Prev/Next) and selected-column deletion
• Quick load button for Sakura opening pattern (5, 5, 7, ●)
• Score metadata controls (title and tempo)
