It would be great to have the ability to create a new feature layer without having to navigate out of the web map.
Many times we're working on a project and need to create a new feature layer and our current workflow is to navigate away from the web map> go to the content tab > create> feature layer> then set up the feature layer schema in the item details page.
A suggestion to streamline this somewhat cumbersome workflow would be to have a way to create these feature layer while the user is in the web map. Ideally under the web map 'add' dropdown there would be an new option for 'create new feature layer' which would then prompt a wizard interface to create the schema.
Just an idea to make everyone's workflows a bit quicker!
