GNOME Activity Journal: Not a Big History Buff
Tracking files you open and edit day-by-day for quick retrieval is a computer feature that should be a built-in part of the Linux desktop but isn't yet. The GNOME Activity Journal attempts to fill that void. It has potential to improve productivity but needs more growth to be really useful.
The Activity Journal was first introduced as GNOME Zeitgeist. It is a tool for easily browsing and finding files on your computer. It keeps a chronological journal of all file activity and supports tagging and establishing relationships between groups of files.
Even in its current puerile form, Activity Journal lets you tap into the concept of seeing recently opened files with an interface that improves upon traditional file-logging functions. It is a history logger but not a true searching tool.
