Feature Request: Improved Shape Recognition and Mathematical Symbol Prediction i

Please expand automatic shape recognition to support open shapes such as arrows, 90° corners, and connected lines, allowing users to draw and hold the S Pen to straighten them.

Additionally, please add handwriting recognition and correction for common mathematical symbols and Greek letters (θ, ω, α, β, σ, π, etc.).

These improvements would make Samsung Notes significantly more useful for handwritten equations, diagrams, and technical notes.
