Oracle, virtualbox, how to import / insert a vdi file when the New and Add buttons are removed from the Virtual Media manager?

situation
	Oracle, please, don’t be Microsoft! It is a shame to remove capabilities from this wonderful software! The “new” and “add” buttons are removed from the Virtual Media manager from version 4.0.0 because simply they are idiot (I can’t find other logical reason). It is shame to reduce the capabilities of a too powerful application.

difficulty level
	2/10 :)
compatibility
	virtual box >= 4.0.0
solution
	To add a vdi info your "Virtual Media Manager" do the follow: - Go at the "Settings" of any virtual machine. If you haven’t any, create a dummy (there is no need to create disk for it). - Go at the "Storage" section. - Click of the “ide controller” (or “sata controller”) - On the same line of the "controller" the two “add” buttons will be appeared, click on “Add hard disk” - Then click on “choose existing disk” - Select the vdi file and will be inserted to Virtual Media Manager. - From this point, you may use this disk in any Virtual machine you want.
attention
	The problem occurred in version 4.0.0 - 4.0.6 at least.
