Changes:

• Improved Hotkeys 
  • Hotkeys now work simultaneously and their effects will be combined
  • Layers now default to "No Change", and you can set the option to "Hide" or "Show" on activation
  • Hotkeys created using the previous setup will still work, but they will all be either "Hide" or "Show" to keep the original effect they used to have.
• Added themes
  • Now you can have the interface in a selection of cool colours!
• Made the Audio Filtering optional, and disabled by default
  • It was brought to my attention that the audio filtering I'd implemented wasn't useful to some, so I made this an optional feature.
