I uploaded new snap, AppImage, and portable builds compatible with Ubuntu 18.04, Mint 19, and the like.

I am sorry for my ignorance (I am just a GUI user, I only use terminal from time to time), but when you talk me about “snap” I only understand that it is the folder that is created in the user folder after using certain programs, such as Shotcut. And the instuctions to install it?
Anyway, thank you very much for answering.
