Cura 4.13.1 on Linux Mint 20.3: Not possible to directly save to the removable drive

[electricar]

Hi,

is there a possibility to save directly to the removable drive and eject it afterwards?
I am using Cura 4.13.1 on Linux Mint 20.3 and I downloaded this zip file:
https://github.com/bigtreetech/Bigtree3DPluginSuit/archive/master.zip

I can save the gcodes without the 3D files directly on the removable drive.

Also is there a possibility to change the color of the created 3D image?
Currently mine are gray and I would like to try the golden one.

Thank you in advance!
