1.5.0

[1.5.0] - 2026-01-28

Added

Focus Mode

• New "Focus Mode" checkbox in Highlight Settings panel
• When enabled, hides all background (non-highlighted) nodes and links
• Shows entire dependency chain regardless of display filters
• Improves visibility when analyzing specific code paths

Navigation History

• Added back/forward navigation buttons with browser-style controls
• Keyboard shortcuts: Alt+Left (back), Alt+Right (forward)
• Tracks entity clicks for easy navigation through code exploration
• Button states update based on history availability

External Import Nodes

• External imports (e.g., os, sys, numpy) now appear as nodes in the graph
• Distinguished with special styling and external type
• Helps visualize all project dependencies including standard library and third-party packages

Changed

Arrow Direction and Visualization

• Reversed arrow directions to better represent code flow
• Module imports: arrows now point FROM importer TO imported module
• Entity dependencies: arrows point FROM entity TO its dependencies
• Improved arrow scaling: scales consistently with zoom level and icon size
• Unified arrow head sizes and stroke widths across all link types
• Dynamic arrow scaling in highlight mode with configurable maximum (18.75x scale factor)

Keyword Filtering Enhancements

• Keyword search now filters at entity level in addition to module level
• Shows full dependency chains when entities match keywords
• Handles import aliases correctly (e.g., import pandas as pd)
• Improves search accuracy for finding specific functions/classes

UI Defaults and Behavior

• Default font size increased to 256 for better readability
• Display panel now expanded by default
• Classes and Functions checkboxes unchecked by default (show only modules)
• Focus mode properly dims labels and icons of non-highlighted nodes
• Improved link opacity handling in highlight and focus modes

Fixed

Display Filter Issues

• Fixed Classes/Functions nodes appearing in highlight mode when filters disabled
• Corrected entity visibility logic to respect display panel settings
• Entity links now properly hidden when corresponding filters are off

Import Handling

• Fixed import statement extraction from AST
• Corrected handling of multi-line imports and comma-separated imports
• Fixed alias imports (e.g., import x as y) appearing in tooltips

Highlight Mode

• Fixed entity-to-entity click highlighting for dependency relationships
• Corrected link dimming in focus mode
• Fixed label and icon dimming to match node highlight state

Arrow Scaling Consistency

• Fixed inconsistent arrow sizes at different zoom levels
• Unified base stroke widths (2px for all link types)
• Arrows now scale proportionally with icons in highlight mode
• Applied proper clamping to prevent excessive arrow sizes

[1.4.0] - 2026-01-26

Fixed

Duplicate Filename Support

• Fixed critical issue where files with the same basename in different directories would collide
• Now uses full relative paths as unique identifiers instead of just filenames
• Module node IDs are now path-based (e.g., src/utils, tests/utils) without .py extension
• Entity node IDs use format path/module:entity_name (e.g., src/utils:helper)
• Module labels still display basenames for readability, with full paths in tooltips
• Search box now shows file paths for modules to distinguish duplicates
• CSV export shows basenames with .py extension for backward compatibility
• Added comprehensive test suite for duplicate filename scenarios

Changed

• Internal node identifiers now use relative paths for uniqueness
• Module identification system refactored throughout core, parser, and visualization layers
• Import resolution improved to correctly match dependencies with path-based identifiers
