Gladys 1.6.7

Gladys is a drag-and-drop shelf that holds things you want to set aside, such as links, text snippets, map locations, contacts, images, photos, emails, messages and much more (even if the application that the information came from is removed)

It works with any app that supports drag-and-drop and keeps you focused by letting you quickly set something aside, without having to consider where it needs to be dropped, or having to constantly switch between apps.
