If possible, it would be cool to have the entry field change when it detects the use case of JS{} or #{}, and allow to open the value in a popup editor like the scripting tab, in addition, utilizing the syntax highlighting.
Sometimes, I have large scripts in the value or range which I feel would be easier to navigate my code if it had the syntax highlighting and popup code editor. Similar to how the matrix props uses it too.
Cheers!
