My $.02 on updating the title bar time:
1. I think it's important that the title bar be the same as the logged time. Now, it's misleading/confusing; I was actually entering my notes to match the time on the title bar! This was useful because sometimes I was away from the computer for several hours and it was good to have to think back what happened then. After entering that, I have next been doing a manual note for right now (the time of return to the computer).
So either update the title bar, or use the old time as the log entry.
2. If you do update the title bar, then surely doing so every minute suffices? If you really want to support people who want to track their time to the second (
), then you could update it every second only for those who enable logging of seconds.
3. BUT if you do make the title bar update regularly, I then lose that useful forced realization "my god, I've been away from the computer for 2 hours!". So what would be ideal would be an elapsed time counter too, which shows how long since it popped up.
4. If you don't want to add a display of elapsed time, then I would vote for leaving the title bar as is (showing the original time of popup), but having *that* (not *now*) be the logged time. Then the user could make a manual entry for *now* if desired (as I have been doing). Or perhaps have an option that if more than the normal popup interval has elapsed since the time of the popup that had been sitting there, then immediately follow it by a "now" popup.)
