My colleague is suggesting to add a detail disclosure icon to a section header in a mobile app. It seems rather cluttered to me given the density of info we already have on the screen. I'm wondering if there is an alternative. For instance, a one-time onboarding modal to highlight the section, and then info in a help section for subsequent viewing? Any thoughts?
Another options is (i) icon, which is used when it's mostly helpful info you are putting onto next screen, and not actions.
As this solution is recommended by guideline https://developer.apple.com/design/human-interface-guidelines/ios/views/tables/, you can easily argue with your colleague.
