Traction's perspective feature is a seldom-used but very powerful capability
that allows you to see what labels were present at a given time in the
past. With
the perspective feature, you can:
rewind to a given point in time, considering only
the label changes that took place before that time, or more generally
restrict the range of time from which label changes
are in effect.
Once you've set your perspective, you'll see the state of labels was
or would have been if only those label changes performed during the perspective
time period were considered. This
allows you to answer questions such as, "What was on the Engineering
project's to-do list on January 1, 2005?" Perspective
effectively ignores all changes to labels that happened outside of the
specified range of time. When
used in conjunction with the time slice (i.e., navigating by date), this
is an especially powerful feature.
When you've changed your perspective, standard Traction skins include
a reminder at the top of the view:
The commands to change perspective are detailed in the Changing Perspective with the Rapid Selector topic. The
command used to reach the example view pictured above was /perspective
