Issue with counting rows for an ingame editor

Hey Red,

I have an issue with my UI right now. I'm trying to create an in-game editor to execute Lua scripts. I'm struggling to properly implement row counters using the UILabel. The problem arises when the code reaches the editor's height; the row counter doesn't update properly because I can't determine which line the cursor is on. The API doesn't provide a method to retrieve the cursor position from the input or anything similar.

Is there a workaround to implement the counter correctly, or could you add a method to get the current cursor position?

The editor currently looks like this:

As you can see in the screenshot, the first line (where the number one is displayed) isn't aligned with the corresponding code line.

I know the code isn't implemented properly, but I'm really looking for a row counter since it helps with reading the code more easily.

The code for the counter looks like this:

private void initLeftTab(UIElement parent){
        UIElement childWrapper = new UIElement();
        childWrapper.style.width.set(2f, Unit.Percent);
        childWrapper.setBackgroundColor(0x3c3c3cFF);


        leftTab = new UILabel();
        float fontSize = leftTab.style.fontSize.get();
        leftTab.style.width.set(100f, Unit.Percent);
        leftTab.style.textAlign.set(TextAnchor.UpperCenter);
        leftTab.style.overflow.set(Overflow.Hidden);
        leftTab.style.marginTop.set(fontSize, Unit.Pixel);


        StringBuilder builder = new StringBuilder();


        for(int i = 1; i < 40; ++i)
            builder.append(i + "\n");


        leftTab.setText(builder.toString());


        childWrapper.addChild(leftTab);
        parent.addChild(childWrapper);
    }

Btw. Is there a way to add rich text?

It would be useful to colorize individual strings so I can implement a syntax highlighter in the future.

Thanks in advance.
