Please add syntax highlighting for most common programming languages in fields that are scriptable or at least a fixed-width font like Courier New.

Right now it's a bit unreadable and hard to find typos, wrong indentation etc. I often tend to write the body of the script in IDE such as IntelliJ IDEA Community and then copy&paste to QB step, but it has one major flaw: I have to remember to replace predefined variable values with vars.getValue(). When script is longer than 50 lines it's easy to miss one or two occurences.

I think that many users would be very grateful for even partial implementation.
