Some feature requests and ideas

• Add the ability to change threshold and ratio using this view [VERY USEFUL]
  • Threshold
  • Ratio
    
  • You can try it in the Soundcraft UI's web interface, it's really fast and convenient to use https://www.soundcraft.com/ui-demo/mixer.html
    
• It's possible to combine compression curve and time graph windows together (just as an idea)
  
  
• Add auto-makeup option [IMPORTANT}
• Add auto-release option
• Add hold parameter (like release but without fade, just keep signal compressed for that time)
• Add fast presets menu
  
• Add factory presets (with the ability to suggest your own presets in PR)
• ADSR-like attack-hold-release visualization with the ability to modify it
  
• Low-cut/High-cut filters as an equalizer
  
• Combine Compressor and Expander in one plugin

The issue groups several compressor feature ideas, including ratio control, auto-release, hold, visualization, filters, and combining compressor and expander functionality, but names no files, tests, or entry points. First select and clarify one request, then locate the relevant compressor UI or processing code; done should be defined by the chosen feature and its corresponding behavior being verified.
