When this returns true you need to: a) call SetDragDropPayload() exactly once, b) you may render the payload visual/description, c) call EndDragDropSo

We don't use BeginDragDropTargetCustom() and duplicate its code because: 1) we use LastItemData's ImGuiItemStatusFlags_HoveredRect which handles items

Pseudo-tooltip. Follow mouse until CTRL is held. When CTRL is held we lock position, allowing to click it.

Lock horizontal starting position + capture group bounding box into one "item" (so you can use IsItemHovered() or layout primitives such as SameLine()

This is essentially a thin wrapper to using BeginChild/EndChild with the ImGuiChildFlags_FrameStyle flag for stylistic changes + displaying a label. T
