- Characters have a unique "gfx" code into the vanilla file, the new coding system of the mod gives to them a photo with using a spritetype and a texture file, rather than directly into the characters/files.

- The version of the game without any DLC is fully functional.

- Deleted decisions folder, some national focus files and events folder, for a maximum compatibility with other mods.

- A new personalized interface file (without the content of the vanilla), for a minimum conflict with the vanilla one.

- In vanilla, if a character exists and is also concerned by a DLC, owners of the DLC have the unique portrait for him, and non-owners have the generic portrait. My goal was to bring a unique photo for a character in these both case: with or without the DLC.

KNOWN ISSUE:
- small portraits for generic generals/admirals?
- small portraits for generals/admirals who come through national focuses, events, and decisions and those who are coded only in history/countries files. When Paradox will decide to update the game files, it will be possible to implement these photos.
Examples : Pranas Saladzius (Lithuania) and all generals of Pakistan.
