Hello Antonino,
Thank you for your contribution, this extension is very good,
What is needed with fivewin is the intellisense of all the functions and their syntax highlighting.
Also, I don't know how to do an intellisense of all the user functions created in a project using workspace,
just like PHP's intellisense works.
I know it's a big job, but if you need support to improve the extension I'm available.
Kind regards
