"The strongest of all warriors are these two — Time and Patience." - Leo Tolstoy, War and Peace

This is a Stopwatch. It currently uses the Numpad and there is no configuration yet. (So you might wanna unbind 5 and 0)

Use /sw or menu list entry to show/hide.

Keybindings:

Num 4: Start the timer downwards. As it reaches 0 it will play a sound. (Also see Loop Mode.)
Num 5: Pause/Unpause the timer.
Num 6: Start the timer upwards.
Num 7: Reset to 0.
Num 8: Reset to last time. This is (most of the time) the last time the timer was paused. It does not save a history.
Num 9: Reset to last saved time. (see Num 3)
Num 2: Activate/Deactivate Loop Mode. When in Loop Mode and reaching 0, the timer will continue at the last time(see Num 8).
Num 3: Save a time. There is a stack of 10 times that will be pushed everytime you save. You can reset to the last saved with Num 9 or scroll through the saved times when timer is not running. Just hover over the Addon and scroll upwards.
Num 0: Go to Edit Mode. The Keybindings will change until you press it again.
