Would be cool to see total run time calculated in the info tab, perhaps with obsolete runs as well.

I don't think that's really relevant to anything. My time would be ~1 hour and 50 minutes, but that's a small percentage of the time I've actually spent running games. :P

LiveSplit will have that beginning with 1.6. It's slightly wrong cause we didn't record the history for splits that you resetted (just those splits, the other splits of a run are all recorded), but we do that beginning with 1.6, but everything beginning with 1.6 will be handled accurately.
