Presets and Customization

Presets

Line Count Explorer now supports customizable presets to quickly switch between different configurations:

Built-in presets:

• Default: General purpose line count thresholds
• LLM Context: Token-based thresholds matching common LLM context window sizes

Custom presets:

• Create your own presets with your preferred settings

Custom Thresholds

Easily define your own threshold levels using comma-separated values:

0, 100, 500, 1000, 2000, 5000, 10000

Presets automatically use the selected indicator symbol set, or you can choose a different set for each preset.

Performance Optimizations

The v2.0.0 release includes significant performance improvements:

• Parallel Processing: Files are processed in batches to maximize throughput
• Prioritized Indexing: Open files and visible files are processed first
• Asynchronous I/O: Non-blocking file operations for better responsiveness
• Smart Caching: More efficient memory usage in large workspaces
• Cancelable Operations: Stop long-running operations at any time
• Progress Reporting: Visual feedback during indexing operations
• Memory Management: Ability to clear caches and reduce memory footprint
• Optimized Algorithms: More efficient line and token counting
• Event-Based Architecture: Reduced polling for better performance
• Workspace Exclusions: Common directories like node_modules are automatically ignored

These enhancements result in:

• Up to 5x faster indexing for large workspaces
• Significantly reduced memory consumption
• Improved UI responsiveness during operations
• Better handling of very large files and projects
