Description

Sometimes I get notifications for reminders or messages in IRC or other applications. These get mixed into notifications for music currently playing and other less important information. It would be nice when I use the applet for notification history that I can remove only the notifications that I don't want to keep history. Right now unless I've missed something it's a all or nothing situation when I want to remove notification history.
