feature: delay in `sample` and `pageSwitch` triggers

[TrizekYT]

Have the ability to set a delay on a sample or page switcher

[Vexcited]

This is a must so here we go, I'll note that...

I will put a delay property on the sample and pageSwitch triggers from any event (onPress, onRelease, ...)

Feature Tracking

• [ ] Add a delay property in trigger.*.sample.
