Hi,

this sounds great. For inspiration - I've attached a screenshot of the gstreamer
debug viewer (a pygtk app). I features some nice functions for analysing logs:

* above the log is a histogram of log events per time. different colors for
log-level (info, warn, error). Additionally warn & error are marked as triangles
at the top of the histogram. Clicking there with the mouse scrolls to the region
in the log-file

* left of the log is a plot inspired by federicos plottimeline.py. it maps the
timestamp currently visible to a linear scale. this helps to spot areas with
lots or no events.

* lots of filtering:
  * clamp start and end time
  * hide levels, categories, ...

* copy lines to bookmark area by double clicking. this helps to compare two log
lines and serves as bookmarks (clicking the line in the bookmark area, jumps to
the line in the log).

Ciao
  Stefan
