 - Rotation dragging follows the selected projected local ring and applies the delta as a local-axis rotation before converting back to Euler transform values. This keeps red, green, and blue controls aligned with the visual local gizmo even after the object is already rotated.
 - Double-clicking an axis resets that single component, while double-clicking the white center hub resets the active transform group.
 - The W/E/R hotkeys switch between Move, Rotate, and Scale while the preview overlay is active.
+- 3D object handles remain visible and selectable in normal preview, layer Edit mode, camera Edit mode, and camera orthographic edit views. Clicking a handle selects that clip and activates the native scene gizmo for the selected 3D object.

 The Transform tab becomes scene-navigation controls for the active camera clip. In FPS mode, the preview accepts WASD/QE navigation plus uncapped mouse look. Free scene navigation now belongs to camera clips rather than gaussian-splat clips.
 
-When Edit mode is enabled while the playhead is over a camera clip, the preview switches to a temporary edit-view camera. Orbiting, panning, and zooming this view does not write transform changes back to the real camera clip; entering and leaving Edit mode blends between the edit-view camera and the timeline camera. In that edit-view, the real timeline camera is drawn as a small projected camera wireframe with a direction/frustum indicator. The full viewport gizmo appears only when that camera clip is selected, and explicit gizmo drags still edit the camera clip through the normal transform/keyframe path. Camera clips do not show a viewport gizmo in the normal view. The 2D layer bounding-box editor is only active in Edit mode when no camera clip is active at the playhead.
+When Edit mode is enabled while the playhead is over a camera clip, the preview switches to a temporary edit-view camera. Orbiting, panning, and zooming this view does not write transform changes back to the real camera clip; entering and leaving Edit mode blends between the edit-view camera and the timeline camera. In that edit-view, shortcuts `1`, `2`, and `3` animate to orthographic Front, Side, and Top views, and `4` animates back to the normal edit-view camera. Edit views draw a projected Blender-style world grid that animates with the camera view instead of snapping as a screen overlay: Front uses XY at `z=0`, Side uses YZ at `x=0`, and Top/free camera uses XZ at `y=0`. In the camera edit views, wheel zoom and Shift-drag/MMB/RMB pan only move the temporary viewport, regular 3D object handles stay visible and selectable, and selecting a non-camera 3D object activates the same native scene gizmo used by the normal preview. The real timeline camera is drawn as a small projected camera wireframe with a direction/frustum indicator. The full viewport gizmo appears only when that camera clip is selected in the normal edit-view camera, and explicit gizmo drags still edit the camera clip through the normal transform/keyframe path. Camera clips do not show a viewport gizmo in the normal view. The 2D layer bounding-box editor is only active in Edit mode when no camera clip is active at the playhead.
 
 Camera rotation keyframes interpolate through the shortest angular path so timeline flights do not spin the long way around when yaw, pitch, or roll crosses a 360-degree wrap. Camera transform keyframes for pan, distance, zoom, forward travel, and rotation render through world-pose interpolation: the camera eye and target are interpolated between keyed world poses, keeping FPS-look moves, zoom-outs, and vertical-look roll moves from drifting away between keyframes.
