The Finder app template can zoom in to a feature that has been selected in the Find results list, but zooming is based on the basemap tile levels, not on the feature geometry. I have an application that is using an alternate basemap that isn't a tiled service. The results is that when you select a feature in the Find results, it doesn't zoom in. The popup for the selected feature appears, but it doesn't have a Zoom To button, like it does in a standard AGOL map. My suggestion (make that a plea): Finder popups should include the Zoom To button.
