In some components / widgetsets DND works OK, at least when DragMode =
mdAutomatic.
I was able to make a GUI for component palette reordering in Lazarus.
There items can be dragged and dropped inside a ListBox and from a
ListView to a ListBox.
Build Lazarus trunk with "EnableComponentPaletteOptions" to test it.

It means the functionality for Drag-n-Drop is there.
BeginDrag / EndDrag is a coupled pair, I was surprised that only the
other one is missing.
It may be a small thing to fix. Maybe I will find time to look at it.

DoDi, docking is a different and more complex issue.
