DTM: Resizing "Edit Code" box for custom JS scripts or HTML

Please add resizing option for the "Edit Code" box for custom JS scripts or HTML in DTM.

The edit box on the overlay is fixed size and too small. Web developers have to scroll for long line of codes. This is very inconvenient.

If we can resize to full screen size, it is easy to see the codes rathar than scrolling again and again.

There are several places where "Edit Code" box is used:

Customize Page Code

Rules: Edit JavaScript / Third Party Script

Data Elements: Custom Script

Thanks,
