How can increase the functionality of the JSL script editor?

[#1]

1, in this script range, automatically highlight other content that is the same as the selected content;
2. How do I change the background color of the selected content when the script editor is in dark mode?

Thanks!

Names Default To Here( 1 );
dt = Open( "$SAMPLE_DATA/Big Class.jmp" );
New Window( "Col List Box Example",
	Col List Box( all, width( 250 ), maxSelected( 1 ) ),
	fontobj = lb = Col List Box()
);
lb << Set Selected( 1 );
lb << Set Selected( 2 );
Wait( 1 );
lb << Clear Selection;

You can do some style changes from Preferences

If you need some new capabilities, check if wish list item already has item you hope to have and if it doesn't create a new wish list item.

No effect. I want to set the selected text background color to white

This is how this selected change was not found.

Thanks!

This is the parenthesized highlight. I found the background color (white).

JSL editor has many nice features which are still missing in other tools.
- multi region select

- copy current line

- full JSL access to run and edit the script (such meta level feature give you extreme power!)

- Edit / Balance (!!!)

But when you work in sate-of-the-art IDEs and JSL Editor in parallel you feel the pain of

- missing AI support

- restricted syntax highlighting

- limited auto-suggestion

- code referencing

- hover-info for variables and functions 

...
No wonder this wish from 2019 Migrate to new JSL code editor got more than 70 Kudos!
Actually, there is just one wish with more Kudos:
Kill process without killing JMP

I don't need your auto-complete code.
Because I don't know English at all
My code is complete through the input method,
I fixed my common JSL fragments in code that I could understand.
So I write code fast, it's just a matter of choice.

Thanks!
