I was looking at the logfile-viewer, and found some issues:

• When the dialog comes up, the tab 'Full log' is selected. So it takes much longer until some content gets shown.
• The dialog cannot be resized.
• No search/find
• No option to rotate/archive/clear the log

Also, it looks like demo-games don't get logged.
(The idea was to run demos to find games with a low amount of lost games, and scan the log for those)
