Edit script but it still run old script

[pouralise]

Explain your use case. You should not need to update scripts dynamically.

I want my end-user can update the script without any coding skill. Like they can setup a script that turn on Light 1, wait 8 second then turn off Light 2, and they can edit it later when they need. They can do that with only tap/swipe item on visulization and the code will change depend on their action.
