I'm toying with the Map Viewer template but one of the things I don't like about it when in small-screen/phone layout is the 50/50 vertical split between the data and the map. Ideally, I'd like it to be all map and for map selections to trigger a slide-up panel containing feature info as laid out according to my needs.
The only way I've seen to use those sliding panels is via Map Widgets/Tools. Is there a way to have a map centric view with your featureInfo being populated into one of these sliding widget panels?
