Still waiting for this 6 years later (though I suspect it was actually first requested within the first year of Gravity Forms’ existence, making the wait even longer). This is the kind of simple, obvious, quality-of-life enhancement that is constantly ignored by the developers and makes GF unnecessarily frustrating to use long-term.
You can suggest this feature directly to the product management team, for consideration when planning future releases, on the Gravity Forms product roadmap page.
