Feature Idea: Hide Bubble banner in version-test only with 60 second timed countdown

Am currently trying to build the correct footer/page height for an app and it’s difficult on the free plan with the Bubble banner in the way. I don’t want to level up to a paid plan before I’m ready to go live given how expensive the plans are.

Can you implement a way to hide the banner in version-test only for 60 seconds (timed countdown) so that I can see the true page height and footer area when building the app?
