# New Amethyst Structure
- `amethyst` - Primary import
  - No longer wrapper crate
    - Enough for simple examples
  - Include ECS, renderer, input, and bare essentials
    - ECS: raw re-export of Legion
    - Renderer
      - Split into 2D and 3D APIs w/ feature flags
        - Compat between 2D/3D. 2D should be able to write to a mesh that 3D can control, without codependency
      - Not Rendy based. See viability of `wgpu-rs` in multithreading, otherwise GFX-HAL
    - Input
      - Keyboard and Mouse
      - Feature flag for controller support
      - Thin adapter for other sources
      - Probably close to what we have now
    - Bare essentials
      - No stages, "helpful" utilities.
      - Minimal to remove boilerplate for Hello World
      - `amethyst_window`, `amethyst_error`
- `amethyst_ext` - Wrapper crate around "high demand" utilities
  - Should not wrap larger crates, like `amethyst_assets` 
  - Should wrap smaller, less-opinionated crates like `amethyst_locale`
  - Should not wrap contextually sensative crates, like `amethyst_networking` and `amethyst_tiles`
  - Introduce utilties from `amethyst_utils`, `amethyst_core`, and old `amethyst`, possibly new ones
    - Ie Stages, background executor
- Other crates should not depend on other Amethyst crates aside from `amethyst`
- Crates to deprecate:
  - `amethyst_config` - No strong features, limited to RON.
