Changes for 2021-02-26:

• Reworked settings loading/saving
  • Settings are now saved in XML format, making it easier for me to expand the way presets work
  • General settings are now saved on application exit, such as the last window position, size, and audio device used

    
    

    • (This addresses https://itch.io/t/925505/audio-input-always-default)
• Added "Loudness gradient" functionality
  • When using Gradient colour mode, you can now tick "Loudness Gradient". This maps the colour scale to the audio level - quieter audio will be closer to colour 1, and louder audio will be closer to colour 2.

[Edit] And naturally I noticed a few bugs just after posting this, so I've fixed those and updated the package as of this edit.
