[edit] Feature Requests

• Alternate representations: pie chart of minute, or ten.
• Reduce 0.1 sec tick frequency for long running timers, to save power.
• "Lap" Function: To record a significant event at a spot in time while leaving the clock running. Maybe Absolute (time since race started) and Relative (length of time since last lap clocked) lap times. Can this be saved to file?
• Include an option for countdown timers, include an option to count up when time has elapsed.
