nWay Stopwatch
You can use 4-way navigation keys for measuring times for each direction.
When you press a navigation key, the direction stopwatch will start timing, and
other direction stopwatch will pause the timing. When you press the paused
direction's navigation key, the stopwatch will resume timing.

for up to 3 events. For example, in a meeting, user wants to monitor the total
speech time for each individual participant. Another example is that user want to
monitor a period of time, how much time he spent on working, browsing web,
dealing with email and meet.
