I would like to request an enhancement to experience builder at least if not all of the AGOL ecosystem to allow developers to toggle the option to have a dark or light basemap be automatically selected based on the user's preferences. Most if not all desktop and mobile devices today switch from light to dark with sunrise/sunset or the user can choose their preference. Most applications also automatically shift with the users preference or default to day/night. It would be great if we could align our maps to also match these preferences and maybe not just the basemap but also the symbology of features as well.
