For over 300kb text scenario, Macro is useful tools, like SCSS Mixin or Utage Macro.
Not like function, Macro store reusable screenplay parts and up speed screenplay editing.
Hope this feature could be add in Naninovel :-)

I'd suggest using gosub and/or custom functions and commands for that.

There was actually a macro-like feature in Naninovel previously (called script defines), but it was removed due to complications with tracking and debugging scenarios. The aforementioned features handle all the cases macro used for in a more manageable fashion.

Thanks, i got it
