App Builder: How to Change Bottom Menu Color from Purple to Red

And also another question.
Within the App builder is it possible to change the menu color at the bottom of the App? Standard it's purple (see image), but I want it to be red.

Hi Ron,

While the feature you're looking for isn't available at Jotform right now, we've gone ahead and escalated your request to our developers. Exactly when or if it's developed depends on their workload, how viable it is, and how many other users also request it. If there are any updates, we’ll circle back to this thread and let you know.

Thanks for your patience and understanding, we appreciate it.
