AppImage

Appimages are portable software that don't need root permission to be run. They can be run without root permission:

Dependency
Most Appimages require on slot zero to be run.

This error can be solved by installing. Slot 0 has version 2 of fuse required by most AppImages, whereas which has version 3 of fuse, this is installed by default if no slot is specified and doesn't solve the dependency problem.
