The clipboard is one thing that we often take forgranted. The concept of copy and paste is almost burnt into our minds, and we use it to move text and objects from application to application.
Often, however, the restriction of having only one object on the clipboard at any one time can be limiting. Enter Parcellite, for GNOME. It keeps a history of your recent clipboard objects, so if you accidentally copy something else, it won’t be gone forever. It is a similar concept to KDE’s Klipper, which I have covered in the past.
