Project Settings → Plugins → Universal Floating Widget. All settings with type, default, and one-line description.

Layout

Max Layout Slots: int32, default 10. Maximum number of layout slots. GetSavedLayoutNames returns up to this many.
Persistence Mode: EFloatingLayoutPersistenceMode, default Config. Config = Saved/Config/FloatingLayouts.ini. SaveGame = requires game integration.
Default Layout On Startup: FName, default LastUsed. Layout to load on startup. Use "LastUsed", "Default", or a specific layout name.
Load Layout On Startup: bool, default true. Load a layout when the subsystem initializes.
Auto Save After Operation: bool, default false. After each drag or resize ends, auto-save to the last-used slot (or Slot_0 if none).

Bounds

Bounds Behavior: EFloatingBoundsBehavior, default Clamp To Edge. Controls whether a dragged panel breaks on edge or stays clamped to the viewport edge.
Break on Edge: Mode name for ending the drag when the cursor leaves the viewport.
Clamp To Edge: Mode name for keeping the drag active while clamping the panel to the viewport edge.
Edge Padding: FVector2D, default (8, 8). Padding from viewport edge when clamping.
Edge Snap Threshold: float, default 8. Threshold for edge clamping and snap behavior. 0 = disabled.

Min Panel Width / Min Panel Height: float, default 100 / 80. Minimum panel dimensions in pixels.
Max Panel Width / Max Panel Height: float, default 0. 0 = no limit.

Resize Handle Mask: EFloatingResizeHandleMask, default All. Which resize handles are enabled (corners, edges, or both).
Resize Handle Size: float, default 4. Hit-test zone (pixels) from each edge for resize handles.
Corner Priority Width: float, default 16. Pixels from corner still considered a corner grab.
Resize Handle Visibility: EFloatingResizeHandleVisibility, default OnHover. When resize handles are visible.

Default Drag Area: EFloatingPanelDragArea, default FromHandle. Which part of the panel triggers drag.
Drag Threshold Pixels: float, default 5. Pixels of movement before click becomes drag.
Bring To Front On Drag: bool, default true. Bring panel to front when dragging.
Show Title Bar By Default: bool, default true. Per-panel can override.
Title Bar Height: float, default 24. Height (px) of the title bar region for TitleBar drag area.

Enable Collision: bool, default false. When false, collision is disabled. When true, panels in the same CollisionGroup resolve overlap during drag.
Collision Gap: float, default 4. Gap (px) between colliding panels. Prevents sticky feel when touching. Only used when Enable Collision is true.

Enable Snapping: bool, default true. Align panel corners/edges to sibling corners/edges when within threshold during drag and resize. Panels need per-widget corner snap opt-in and matching SnapGroup to participate.
Snap Threshold: float, default 10. Distance (px) within which to snap to an eligible sibling corner.
Snap Release Threshold: float, default 14. Distance (px) beyond which an active snap releases during drag. Lower values make pull-away feel less sticky.
Snap Gap: float, default 4. Optional gap (px) when snapped. 0 = flush alignment.

Enable Grid Snap: bool, default false. When true, drag and/or resize snap to a global grid inside the safe zone.
Grid Snap Mode: EFloatingGridSnapMode, default CellSize. CellSize = fixed pixel spacing. Divisions = evenly divide the safe zone. PerfectSquares = subdivision behavior.
Grid Snap Size: float, default 32. Grid cell size in pixels when mode is CellSize.
Grid Snap Divisions X / Y: int32, default 8. Number of equal columns/rows when mode is Divisions.
Perfect Square Divisions: int32, default 1. In PerfectSquares mode, level 1 is baseline; higher levels subdivide by powers of two; level 0 makes it coarser.
Enable Grid Snap For Drag: bool, default true. Snap panel top-left positions to the grid during drag.
Enable Grid Snap For Resize: bool, default true. Snap the moving edge/corner to the grid during resize.
Show Grid Overlay: bool, default false. When true, Floating Grid Overlay widgets render the active grid and safe-zone border.

Grid Overlay Minor Line Color: FLinearColor. Color of minor grid lines in the overlay. Only when Enable Grid Snap and Show Grid Overlay are true.
Grid Overlay Major Line Color: FLinearColor. Color of major grid lines.
Grid Overlay Safe Zone Color: FLinearColor. Color of the safe-zone border in the overlay.

Dynamic Anchor During Drag: bool, default true. During drag, update the anchor to the nearest zone so the widget stays in the same relative spot on resolution change.
