The dragging support for collections needs improving in three ways.
- First, it's not possible to drag a resource tab onto the collections page. It is possible to drag tabs into "Hidden Resources", so for consistency and convenience it should be possible to add them to collections as well.
- Second, it's not possible to drag multiple resources from the library to anywhere. You can make multiple selections, but when you drag them only one resource drags.
- Third, it would be nice to drag resources from search results, either to a new tab, or to Collections.
