Here is another widget for the Web App Builder.
 
Live Preview Site
Web AppBuilder for ArcGIS | Help - eLocate Widget
 
Features:
- Locate and address (like the search widget, but gives you the ability to limit the address search to the maps current extent).
 - Locate coordinates using user defined spatial reference coordinates (i.e. DMS, State Plane, Etc).

- Fixed issue with result tab being disabled and widget attempting to select the results tab.
 - Fixed feature popups not working when the address inspector is activated and widget is closed.
