Some mouse-only actions

Hi,

I use Dynalist as an everyday planning/note taking tool and sometimes miss a few mouse-only actions that seem quite easy to implement.

First is the ability to create a new sibling item via context menu. There is “Add note” menu item, but no “Add item”:

Second is the ability to move an item inside another item by drag-and-drop. Now when I drag an item onto another item it becomes a sibling:

But I think it would look natural for a user to drop the item directly onto another item and make it a child.
