I found it really useful to put any library in the send to context menu for folders that have alot of mixed content so you can right click to add to a library. This can be accomplished by going to folder options and showing hidden files. The send to folder can then be located. Users\AppData\Roaming\Microsoft\Windows\SendTo. Then you can hide hidden files again. This works really well it essentially will allow you to add (without physically moving) a file to any library through the context menu.
