Create my own Library(?)

Hey Guys,

Although I am new to Wappler (and Web apps in general), I would like to explore things and get organized as I go forward.
My question is, how do you guys organize your scripts (successful coding or ways of making tasks work)?
I know this is a very “general” question, but as a matter of fact I am just asking how do you reuse coding parts that took you long time developing the first time.
I hope you understand what I mean.
It would be very helpful to hear from experienced users how they handle a kind of “template/library” system on their creations.
Thanks in advance!
