Bugfix: restore open file → plot pipeline broken by refactor

Version 2.3.3 🚀

📈 Plotting

• Plot rendering performance has been improved across all modes.
• 3D zooming and rotation are smoother and more responsive.
• Support for 2D parametric functions (x(t), y(t)) has been added.
• Axis names are now used consistently in plot data headers.
• 3D axes are disabled when not required to ensure consistent rendering.
• Default plot styles have been updated:
  • 2D & 3D functions render as points by default instead of lines.

🖥️ Interface

• Input options have been simplified to show only supported modes.
• Parametric input is available for 2D functions.
• The main window layout has been adjusted for improved spacing and alignment.

• Many bugs detected after previous version were fixed.
• UI Font changed from Cantrell to Inter. (Better Greek coverage)

Version 2.3.2

🎨 UI / UX Improvements

• Math Symbols panel added for easy input of Greek letters and math symbols.
• Enhanced dark mode support; the theme now remembers your preference.
• Notes tab now scrollable for better readability.

📊 Plotting & Data Handling

• Simplified plotting workflow: 3D axes now render more reliably, and all plot types use consistent data columns.
• Improved CSV support and dataset information display, including additional statistics.
• SIF function mode now automatically enables the ranges panel when equations are entered.

🔧 Build & Packaging

• Bundled fonts for better display of special characters.
• Snap store support added for easier installation.

📚 Documentation

• Updated README with clearer build instructions and download options.
