Suggestion

format_jpeg_write_settings_order.png

• unify order of JPEG write settings
  in Settings and Export dialogs
  
  Note: technically correct order is shown below, but this is not required for the user interface

  Step	Stage	Purpose
  Subsampling	Pre-processing	Reduces color data resolution
  Smoothing	Pre-processing	Filters noise to improve compressibility
  DCT	Transformation	Converts pixels to frequency coefficients
  Huffman Optimization	Entropy Coding	Creates custom tables for better compression
  Progressive	Formatting	Reorders data for multi-pass loading
