Customizable shadow parameters




Simple extension to modify Muffin (Mutter) shadow preferences.


  • Shadow presets
  • Custom presets creation (see settings-schema.json)
  • User settings backup (also located in settings-schema.json)


Extension was created and tested on Cinnamon 3.2, but it should be compatible with older versions.

I like this extension .... is it now compatible with LM 19.2 and the corresponding Cinnamon version ?

Linux Mint 19.2 is now in beta and it features Cinnamon 4.2.2. This extension is not compatible with it. Could you please update it for compatibility with Cinnamon 4.x?
It's a shame this extension seems not to work at all with Cinnamon 4.0.

Hello Mikhail-Ekzi, thanks for the great extension. It runs fine. I searched for it. But I have "gedit" installed and that has a shadow :( Can you please do something there?
