The module operation should be encapsulated in a black box

The module operation should be encapsulated in a black box. Because normal users do not get used to this term.

I think this term is for
engineers. For the user, they should have simple windows or simple commands to install the software and do the related configuration.
E.g. for install and configure the Chinese pinyin input.

Bodhi uses Module to load and install the feature.
Given this is new to me , so I do some checking.

I find it is
used in Ruby programming Language:
"Modules

Modules are a way of grouping together methods, classes, and constants. Modules give you two major benefits:
Modules provide a namespace and prevent name clashes.
Modules implement the mixin facility."

This module way, maybe excellent for coding,
but NOT for users without
software background.

so in backend, we don't need to change any things,we can continue to use Module concept in OS development.
But in the front end ,
it should be hided from users. For users, make is simple by just
pick and add. Make it as easy as to install from Bodhi App
