 - `commands.lua` Extra helper commands used internally by doom-nvim.
 - `ui.lua` Loads the user's colorscheme from the `doom.colorscheme` field.  Falls back to `doom-one` if a colorscheme isn't set or is broken.

+  c. `handle_user_config` will handle the user imported packages, autocmds and vim cmds from the `use_*` functions (from user's `config.lua` file).
