Custom function usage for UDL

[Delta]

We’ve all been there at some point.
We’ve made a function in some language at some point in time.
But there’s no way to have the function in syntax highlighting and be able to see what the function needs to call.

I have some ideas on where the NP++ admins and programmers could use this kind of development.
I’ve worked with gui development and I think that this new form of syntax highlighting could be extremely useful especially for programmers who are very function oriented. I’m not personally but I do think it’s a very useful idea.
