@mkart-vrn there are help docs available. This can be exposed by showing them via the edit menu page and saving the changes. Alternatively, on the scripting datasource page. There are question marks you can click on that will render a sidebar to the right with a detailed explanation and or help docs.
I also encourage you to look through the forum and see what has been accomplished by other mango power users.
As for delays, there is a delay option so you can delay the firing of a script upon a trigger as well as using a cron style scheduler. There's also an advanced scheduler which you can attach event actions to for triggering scripts, running a local application, even setting point values.
Feel free to raise more forum posts in user help to fill in any blank areas. I'm on here throughout the week usually. I'm currently remote however so expect up to week delays...
