Execute a Query - SQL Script box should be expandable

When building a SQL Script for use with my workflows (especially when substituting parts with NAC variables) - there's very little space to work in. It's frustrating to use, and using arrow keys to navigate the script just acts as [Home/End], jumping to the start or end of the whole script, rather than moving up/down one row.

It would be really helpful if the SQL Script box could be expanded, much like the [Send an Email] connector allows you more space to edit the body of an email.
