• Pomodoro Timer: Integrate a Pomodoro timer to help users stay productive. Notify users when a work session ends and when it’s time for a break.
• Task Reminders: Implement notifications to remind users of upcoming deadlines.
• Reports and Analytics: Visualize the time spent on each task and project using graphs or pie charts.

Create a weather dashboard that provides real-time weather information and alerts based on user preferences. The application should include:

• Weather Data: Display real-time weather data using a weather API (temperature, humidity, wind speed, etc.).
• Location Management: Allow users to add multiple locations (cities) and view weather data for each.
• Alerts: Set up weather alerts for specific conditions (e.g., rain, snow, temperature thresholds).
• Forecast: Display weather forecasts for the next 5 days, including temperature and conditions.
• User Preferences: Allow users to customize the units (Celsius/Fahrenheit), preferred weather conditions, and alert thresholds.

Develop a desktop photo editor that lets users apply filters and effects to their images. The application should include:

• Basic Editing Tools: Crop, rotate, resize, and adjust brightness/contrast.
• Filters: Implement a set of predefined filters (e.g., black and white, sepia, vintage).
• Effects: Allow users to apply advanced effects like blur, sharpening, and vignette.
• Layer Management: Enable users to work with layers, allowing multiple changes to be applied non-destructively.
• Export Options: Let users save the edited images in different formats (JPEG, PNG, TIFF).

Develop an interactive chess game where a user can play against an AI opponent. The application should include:

• Chessboard Interface: Display a functional chessboard with movable pieces.
• Game Logic: Implement chess game rules (movement, check/checkmate, etc.).
• AI Opponent: Implement a basic AI that can make valid moves using a decision-making algorithm (e.g., minimax).
• Player vs. AI Mode: Allow users to play against the AI or another user.
• Game History: Track and display the history of moves in a game.

Design a desktop recipe manager and meal planner that helps users organize their recipes and plan meals for the week. The application should include:

• Recipe Storage: Add, edit, and categorize recipes by ingredients, cuisine, and difficulty.
• Meal Planning: Let users plan meals for the week, with automatic ingredient lists.
• Shopping List: Generate a shopping list based on the meals planned for the week.
• Nutritional Information: Display nutritional information (calories, protein, carbs, fats) for each recipe.
• Recipe Sharing: Allow users to share recipes with others via email or social media.

Create a 3D object viewer that allows users to interact with 3D models of various objects (e.g., car, building, or product). The application should include:

• Model Import: Support importing 3D models in standard formats like STL, OBJ, or FBX.
• Interaction: Enable users to rotate, zoom, and pan the 3D object. Use mouse or touch gestures for interaction.
• Shading and Materials: Apply realistic materials and textures to objects, including different shading models (Phong, Gouraud, etc.).
• Lighting Effects: Allow users to adjust lighting sources and observe the effects on the 3D object.
• Annotations: Add the ability to place text annotations or highlights on the 3D model for specific features.

Create a node-based GUI for designing and applying image filters. The application should allow users to visually connect different nodes to build a custom image processing pipeline. The system should include:

• Node Types: Include basic nodes for common image processing tasks such as blur, sharpen, grayscale conversion, edge detection, and color adjustments.
• Node Customization: Allow users to configure each node’s parameters, such as filter strength, color balance, and kernel size, using sliders or input fields.
• Node Connections: Enable users to connect nodes with simple drag-and-drop functionality to define the flow of image data.
• Real-time Preview: Show the result of the processing in real time, updating the image as nodes are added or modified.
• Undo/Redo: Implement undo and redo functionality to manage changes to the node graph.

Create a node-based interface for building and training machine learning models. The application should allow users to build models by visually connecting different processing steps and training algorithms. The system should include:

• Node Types: Include nodes for data preprocessing (normalization, feature extraction), model layers (e.g., Dense, Convolutional, LSTM), and training operations (e.g., loss functions, optimizers).
• Model Visualization: Allow users to see a graphical representation of the model architecture, similar to how neural network layers are visualized in tools like Keras or TensorFlow.
• Parameter Adjustment: Enable users to configure parameters for each node, such as the number of neurons in a layer or the learning rate for an optimizer.
• Training and Testing: Allow users to input training data, initiate model training, and visualize performance metrics (e.g., accuracy, loss) in real time.
• Export/Import Models: Allow users to export the trained model in a format compatible with other frameworks (e.g., TensorFlow, PyTorch) and import pre-existing models to modify their structure.

Develop a 3D data visualization dashboard that allows users to visualize complex data in 3D space (e.g., financial, scientific, or geographic data). The application should include:

• Data Input: Import data in formats such as CSV, JSON, or directly from an API.
• 3D Plotting: Plot data points in a 3D space, representing different dimensions of the data (e.g., x, y, and z axes).
• Interactive Controls: Allow users to interact with the visualization by rotating, zooming, and panning to explore the data.
• Color Mapping and Grouping: Use colors or shapes to categorize and distinguish different data groups or ranges.
• Dynamic Updates: Implement real-time data updates and transitions, with the ability to visualize changes over time.
