GPSLog Labs uses thumbnail icons to help you identify your logged activity at a glance, without having to load the full map.

These thumbnails indicate scale by showing 1km grid lines.  The start point of the log is marked as a small green square, the stop point as a small red square.

For example, the following thumbnail shows a log of approximately 65km:

And one of 2km:

In the inbox, "junk" logs will be indicated by half-size thumbnails:

Routes also show thumbnails of their altitude profiles.  In these icons, the grid represents 10km along the horizontal axis, and 100m in the vertical axis.

For example, below is of a 70km log that climbs a 600m hill:

And a 14km log with less than 100m altitude variation:

There are also "clock" thumbnail icons that indicate the duration of activity and sessions.  These show a shaded segment on a 12 hour "clock", with a green marker for the start time, and a red marker for the stop time. 

The icon below indicates a session that starts at 6:30 PM and goes for 3 hours until 9:30 PM:

If a log or session is longer than 12 hours, a thinner band indicates that it has "wrapped" around the clock.  A session that starts at 6:30 PM and goes for 15 hours until 9:30 AM would have the following icon:
