Overview

This release focuses on graph usability improvements, performance optimizations, and UI enhancements based on community feedback.

New Features

Graph Screen Space Optimization 📊

  • Removed Unnecessary Padding: Eliminated excessive padding and card wrappers around graphs to maximize screen real estate
  • Compact Layout: Graphs now use space more efficiently, allowing more data to be visible at once

Frequency Locking 🔒

  • Click to Lock: Click anywhere on a graph to lock the cursor at that frequency
  • Visual Indicator: Locked frequency is clearly indicated with a lock icon and Hz value
  • Remember Position: When the mouse leaves the graph, the cursor position is remembered and remains visible
  • Easy Unlock: Click the 'X' button to unlock and return to free cursor movement
  • Works in All Views: Frequency locking is available in both compact and expanded graph views

Improved Graph Legend 📈

  • Integrated Live Values: Replaced floating tooltips with integrated legend display
  • Always Visible: Legend shows live values at all times, reducing visual clutter
  • Better Performance: Removed tooltip hover calculations that were causing lag
  • Compact Mode: Two-column layout in compact mode, expanding to more columns when space allows

EQ Editing Improvements 🎛️

  • Per-Graph EQ Editing: EQ edit mode now applies only to the selected graph, not all graphs
  • Context Menu Control: EQ context menus (for adding filters and parametric EQ) only appear when in EQ edit mode
  • Clearer State: EQ button shows on all graphs that support EQ, making it clear which graphs can have EQ applied

Max SPL Graph Enhancements 🔊

  • Thermal and Mechanical Limits Toggle: Added "Limits" button to show thermal and Xmax (mechanical) limits
  • Limit Visualization: Displays the non-constraining limit as a dashed line (e.g., if mechanical is limiting, shows thermal limit as dotted)
  • Detailed Legend Information: When limits are enabled, legend shows:
    • Thermal limit (THERM) with dashed line indicator
    • Xmax limit (XMAX) with dashed line indicator
    • Excursion: X/Ymm (Z%) format showing excursion at limit vs driver Xmax
    • Power: X/Y W (Z%) format showing power at limit vs driver Pe
  • All limit information updates dynamically as you hover or lock the cursor at different frequencies

Improvements

Performance ⚡

  • Faster Animations: Graph animations now run 2.5x faster for more responsive interactions
  • Optimized Rendering: Improved graph rendering performance, especially in compact mode
  • Reduced Re-renders: Better memoization and state management to prevent unnecessary re-renders

Visual Enhancements 🎨

  • Dark Mode Graph Lines: Improved grid line visibility in dark mode for better readability
  • Input Power Visibility: Power input moved to a pinned bottom bar with improved visibility and better alignment
  • Better Contrast: Enhanced visual contrast across all graph elements

Bug Fixes

  • Fixed React Render Error: Resolved "Cannot update a component while rendering a different component" error in EQ overlay system by deferring state updates to avoid render-phase updates
