I've noticed that if I try to drag a DocumentContent out of the main window to become a floating window, it takes several seconds for the new window to come up. This is because I have Xceed grid, a heavy component inside that DocumentContent.
Is there a way to optimize this? E.g. I don't mind turning something like "Show Contents when dragging" off on initial drag-out. Simply displaying a square or a static snapshot of the tab is enough.
Check out Google's Chrome browser. If you take a tab and try to drag it out, it displays a smaller snapshot of that tab while dragging. Then upon releasing the mouse, the full floating window is created.
