When re-parenting a component in the browser tree, you should be able to drag and drop the component into the spot where you want it to end up. If I release the mouse where the blue line is in this picture, the component should become a child of the top-level node. Right now the blue line just misleads the user into thinking the component will be moved there, even though nothing happens. The program currently requires the user to drop the component onto the parent node itself.
