By adding a leay function, very similar to the new inching function would allow to implement some applications wher you need to control things in a certain order.
For example to control heating in a swimming pool, where you need to turn the water pump and heading source in a certain order:
Start heating pool:
- Turn water pump and after a minute turn heating on
Turn heating off
- Turne heating off and 1 minute later turn water pump off
There could be other use cases where you may need to delay the start, like an alarm system that need to give you time to disarm the alarm after the sensors are activated.
