Default Layout On Startup: FName, default LastUsed. Layout to load on startup. Use "LastUsed", "Default", or a specific layout name.

Bounds

Bounds Behavior: EFloatingBoundsBehavior, default ClampAlways. How panels interact with viewport bounds.
Snap Back Trigger: EFloatingSnapBackTrigger, default OnLayoutLoad. When to snap off-screen panels back (if BoundsBehavior = AllowOffScreenWithSnapBack).
Edge Padding: FVector2D, default (8, 8). Padding from viewport edge when clamping.
Min Visible Area: float, default 50. Minimum visible area (px) before a panel is considered off-screen.
Edge Snap Threshold: float, default 8. When dragging to the edge padding, snap and stay on edge until user drags away. 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.
