We need to be able to start, stop, and reset each stopwatch independently. We can do this by adding a few more methods to the `TimeDisplay` class.
```python title="stopwatch06.py" hl_lines="14 18 30-44 50-61"
```python title="stopwatch06.py" hl_lines="14 18 22 30-44 50-61"

```
Here's a summary of the changes made to `TimeDisplay`.
- We've added a `total` reactive attribute to store the total time elapsed between clicking that start and stop buttons.
- We've added a `total` reactive attribute to store the total time elapsed between clicking the start and stop buttons.
- The call to `set_interval` has grown a `pause=True` argument which starts the timer in pause mode (when a timer is paused it won't run until [resume()][textual.timer.Timer.resume] is called). This is because we don't want the time to update until the user hits the start button.
- The `update_time` method now adds `total` to the current time to account for the time between any previous clicks of the start and stop buttons.
- We've stored the result of `set_interval` which returns a Timer object. We will use this later to _resume_ the timer when we start the Stopwatch.
- We've added `start()`, `stop()`, and `reset()` methods.
