multiple stopwatches

[wfaulk]

Is your feature request related to a problem? Please describe.
I find myself having to time a total event and then also an activity that takes place during that event, but which starts and stops. In general, though, it would be nice to be able to time multiple simultaneous events.

Describe the solution you'd like
Multiple simultaneous stopwatches, much like the multiple simultaneous timers that already exist.

Describe alternatives you've considered
It's possible to note a begin time for a surrounding event and then a stop time, while recording the stop-start sub-event with the stopwatch, but then I'm avoiding the stopwatch for something it was made for.

It's also possible to tap "lap" each time the sub-event starts or stops, but then you have to keep track of which laps were on and which were off.

It might also be possible to use a timer as a stopwatch by setting it for a time longer than is expected and then subtract the remaining time to find the total length, but, again, that's what a stopwatch is for.

Another use case for this feature is to have different amounts of time you want to assign /accumulate to different categories. It would therefore be nice to have separate named stopwatches, just like there are for timers.

EDIT: it turns out that for the use case I mentioned above, the Simple Time Tracker app is a full featured open source solution.
