Were the tools showing more than just a simple time line of logs? Having just a time-line plot of when things happen is not that useful. For example, LTT had some time-line graphing of events. There is either too much data or too little data on the screen . When showing a signficant portion the time line there is a massive clutter of items in the time line in addition to the few events you are interested in. When zooming in one only sees the single event, not the other interesting event(s). Really want visualization tools declutter and filter out as much as possible from the graphics. -Will
