• When opening the New Parameter dialog it should auto focus on the keyword field.
• Pressing Enter should submit the dialog.

The two above are to support keyboard only workflow, where you would hit Cmd+P -> Enter keyword -> Hit Enter, and can continue writing your query.

• "This is the keyword that will be added..." string always being split into two rows: maybe we should just show the keyword (the {{ ... }} part) on the second row?

• There should be some indication that we saved the query after hitting OK (when we save).
