I'd like to see more options to configure popups in AGOL webmaps. Users should be able to configure both size and placement of popups. For example, I may want the popup to display like a panel on left side of map. Optionally, these configurations could be done in apps like web app builder, or other configurable templates.
Also, it would be useful to control how media is displayed better. For example, I'd like to display multiple charts in a popup, stacked vertically and just have user scroll or swipe to see them all.
