 ### Phase 2 - Selection + Transform + Undo
 - Click-to-select (Movable actors only), Ctrl+click multi-select
-- Custom gizmo (R/G/B arrows + cones, SDPG_Foreground, constant screen size)
-- Translate/Rotate/Scale via gizmo drag, hotkeys E/R/T
-- Snap to ground (End), soft-delete (Delete + confirmation dialog)
+- Gizmo modes:
+  - Translate (Z): arrows + cones, world or local space
+  - Rotate (E): quarter-arc rings (ProceduralMesh), dynamic octant facing, local orientation during drag
+  - Scale (R): arrows + cubes + center cube (uniform), always local space
+- World/Local space toggle (UI button), Scale always local
+- Snap system: configurable translation/rotation/scale snapping (UI toggle + value field)
+- Snap to ground (End), soft-delete (Delete + in-game confirmation dialog)
 - Undo/Redo (Ctrl+Z/Y, 50 action stack)
 - Properties panel + toolbar UI
-- Materials: M_PS_Editor_Gizmo (Unlit, "Color" param, Translucent, Disable Depth Test)
-- Selection outline: auto-generated PP material, BL_SceneColorAfterDOF, Lerp blend, color AF1500, 1px
-- Outline material auto-created via OnPostEngineInit, uses InvSize for resolution-independent offsets
+- Selection outline: auto-generated PP material, BL_SceneColorAfterDOF, color AF1500, 1px
+- Rotation: screen-space direction with magnitude speed, fixed axis during drag
 
 ### Phase 3 - Object Spawning
 - SpawnableComponent: marker on BPs (name, category, thumbnail)
-- SpawnCatalog DataAsset + Factory for easy creation
-- SpawnManager: spawns in front of camera, tracks all spawned actors
-- Catalogue UI: thumbnail cards (80x80), click to spawn, grouped by category
-- CaptureAllThumbnails on DataAsset: auto-generates from UE thumbnails
-- Spawn undo/redo, auto-deselect hidden actors

 ### Phase 4 - JSON Serialization
-- SceneData USTRUCT (Version, SceneName, Timestamp, Actors[ClassPath, Location, Rotation, Scale])
 - SceneSerializer: Save/Load/Clear/GetSavedSceneNames
 - Files in Saved/PS_Editor/Scenes/{name}.json
