Script textareas do not have syntax highlighting or code linting

When implementing script in the new process designer, the textarea does not provide any code highlighting or linting (syntax checking). This makes development very slow as missing a simple quote is not caught until there is a full deployment and error shown in the logs

Adding in something like google code-prettify and a linter to check for simple syntax errors would be a huge help.

Currently I write scripts in an external editor for highlighting and syntax then copy and paste into PAM.
