When I click on "Save as Collection" from the Library tab nothing seems to happen.
If you open the library pane (rather than just click for a drop down) and then select the resources it will create an unnamed collection. If you try to do it from the drop down it does not work. I don't know if that is a bug or intended behavior
This is a bug, and it has been reported. See here for more details.
