In short, allow us to design custom pop-up styles and content. There's no way to customize your design to make the map look outstanding. Quite frankly, all AGOL web maps look horrible when it comes to the pop-up.
Ideally I'd like to be able to have charts, images, graphics, and at the very least change the colors and fonts, spacing, and add symbols. Take inspiration from here: https://www.hudsandguis.com/home/2015/12/7/spectre-007
And ya, that movie is from 2015.... we should be way ahead tbh.
Also custom labels......
