 This is a normalized reconciliation of the VistaPro manuals, MakePath guide, screenshots, and current OpenVistaPro implementation.
 
 Status counts by normalized feature family:
-- Implemented: 11
+- Implemented: 12
 - Partial: 5
-- Planned: 4
+- Planned: 3
 
 Notes:
 - “Implemented” means the current codebase has a working, tested slice for that family.

 | Fractal / synthetic terrain generation | VistaPro overview calls out fractal landscapes and generated terrain. | Partial | `src/terrain.rs` (`plane`, `radial_hill`), `src/app_state.rs` presets. | Current terrain generation is only deterministic fixtures, not a true fractal/noise terrain engine. |
 | Camera and target placement | VistaPro 2 / 3 manuals: “Setting Camera and Target”; screenshot workflow uses camera/target gadgets. | Implemented | `src/scene.rs` (`Camera`), `src/app.rs` (camera position/target controls), `src/app_state.rs`. | Only the core position/target slice exists; there is no map-click placement UI yet. |
 | Lens / range / orientation controls | VistaPro manuals describe lens/range, bank, heading, and pitch controls. | Implemented | `src/scene.rs` (`Camera.orientation`, `fov_degrees`, `near_range`, `far_range`), `src/render.rs` perspective renderer, `src/app.rs` explicit heading/pitch/bank and lens/range controls. | The modern shell keeps the camera model explicit while staying intentionally simpler than the legacy lens matrix and stereo workflows. |
-| Water / sea level, tree line, snow line, haze | Manuals repeatedly mention tree line, snow line, water level, haze, and atmospheric tuning. | Implemented | `src/scene.rs`, `src/app.rs` sliders, `src/colormap.rs`, `src/render.rs`. | Rivers/lakes are still missing, but the core elevation-band controls are present. |

+| Rivers and lakes | VistaPro manuals explicitly mention rivers and lakes as adjustable landscape features. | Implemented | `src/scene.rs` (`Hydrology` lake/river overlays), `src/app.rs` hydrology controls + reset button, `src/app_state.rs`, `src/render.rs`, `src/scene_file.rs`, tests in `src/scene.rs`, `src/render.rs`, and `src/app_state.rs`. | The first clean-room slice now exposes editable lake/river overlays; routed-water simulation and drainage maps can grow later. |
 | Light direction and custom lighting | Manuals discuss sunlight placement and lighting experiments. | Partial | `src/scene.rs` (`Light`), `src/render.rs`, `src/app.rs` (light state exists in the scene model even if UI is minimal). | The current model is much simpler than VistaPro’s lighting workflow and lacks richer light controls. |
 | Vertical exaggeration | VistaPro manuals describe vertical scaling / scene exaggeration controls. | Implemented | `src/scene.rs` (`Scene.vertical_exaggeration`), `src/app.rs`, `src/app_state.rs`, `src/render.rs`, tests in `src/render.rs`, and scene-file round-trips in `src/scene_file.rs`. | The basic scene-level exaggeration slice is now wired through the shell, renderer, and scene files; future work can explore per-tool or legacy-style exaggeration workflows. |
 | Color maps / palettes / texture image loading | VistaPro 3 manual includes loading PCX images, adding texture, and saving/loading color maps. | Implemented | `src/scene.rs` (`Palette` thresholds/bands + colors), `src/app.rs` color-map editor, `src/colormap.rs`, `src/render.rs`, `src/script_exec.rs`, `src/scene_file.rs`. | Palette import/export and PCX/texture loading remain future clean-room work. |

 | Terrain / import | Load Landscape, Import, terrain source selection, generated terrain presets | Left dock or collapsible section | Partial | The current shell exposes project-owned terrain presets (`Plane`, `RadialHill`) and a working heightmap import action; legacy format import UI is still absent. |

 **Status:** Tasks G1–G4 have landed. `src/app_state.rs` holds testable app state and `AppAction` reducers; `src/app.rs` and `src/bin/openvistapro_app.rs` provide the `app`-feature `eframe`/`egui` shell. The shell now docks terrain, scene/camera, render, import, script, path, and project controls around the CPU top-down/perspective preview, with a bottom status bar and backend-backed import/script/path actions.
 The shell map is tracked in [`docs/knowledgebase/ui-panel-map.md`](../knowledgebase/ui-panel-map.md).
 
-Remaining UI roadmap: Task G5 (WGPU renderer backend) plus the still-open gaps — legacy menus/dialogs, richer file/project chrome, animation-frame export, deeper script/path editors, hydrology controls, and palette import/export / texture loading. All of it stays clean-room: no proprietary VistaPro assets, menus, or screenshots enter the repository.
