 TODO
-Feat UX: Use config files and logic overrides
-
-## Requirement:
-- Decouple logic using files: .bashlava_env.sh and .bashlava_env_override.sh
-- At the moment, its too complex for a new user to configure bashlava
-- Let avoid having multiple place to define them, source components, source .md
-- Few array that are configs. They should be all together under the same block of code.
-
-## Functional impacts:
-  - Dockerfile file is not the place to store config anymore (old logic from https://github.com/firepress-org/ghostfire)
-  - Logic for .bashlava_env_override.sh, needed for this env var
-      APP_NAME="notset"
-      GITHUB_USER="notset"
-      APP_VERSION="0.0.1"
-  - Update Show_Version()
-  - Update Show_Tag()
-  - Update Show_Release()
-  - remove remove v_and_t()
-  - remove Core_Load_Vars_General()
-  - remove Core_Load_Vars_Dockerfile()
-  - remove Core_Check_Which_File_Exist()
-  - File: to check VERSUS file to source
-  - Extended Test: Show all var and config (debug)
-  - Think about private scripts trigger
-  - README docs are still missing, but its ok at this point
-  - Impact on: #4, #8, #10
-
-
-TODO private scripts
-logical flags to manage under /private/*
-Need to check if files exist /private/* when DIR private exist
-Need logic to manage file under /private/*  fct VERSUS public fct
-overide like:
-- favorite URL
-- custom_fct_opensite="true" # during pr, merg
-- custom_fct_help="false"
-- set a new config flag: debug="true"
+PR Title: FEAT: 4 updates (configs, source, private). See PR
 
+- Add new config / CFG_RELEASE_POPUP
+- Add new config / CFG_LOCK_INIT
+- Source .bashlava_env.sh directly from bashlava projet (not from pwd)
+- Logic for private scripts is already well managed
+- Impact on: #4
