Advanced algebraic input
- Scientific ALG keypad with prefix actions (`f/g`)
- Keyboard or keypad entry
- Live rendered math preview with pan and pinch zoom
- Build, inspect, and refine long expressions comfortably

Rich math objects
- Real and complex numbers (Cartesian/Polar behavior)
- Fractions, vectors, and matrices
- Matrix/vector operations including products, transpose, determinant, inverse, dot and cross products

Units, constants, and formatting
- Integrated units workflow in expressions
- Access to constants database in ALG flow
- Shared global number formatting between RPN and ALG

Functions and persistence
- Define and edit functions from both RPN and ALG workflows
- Coherent shared function database
- Draft and editing improvements for smoother continuity

Statistics and scientific tools
