ActionTiles is the creator of a web-based control panel (or dashboard) for SmartThings. Sign up for an ActionTiles account (with an email address and password not related to your SmartThings account) and connect this to one or more SmartThings Locations and its Things. You can then build any number of distinct Panels with any combination of Thing Tiles, and a few special Tiles like direct video streams, clocks, and web shortcuts. Panels can be securely shared and unshared with other ActionTiles users. ActionTiles only offers views of and commands to Things; it does not provide other SmartThings app functions like adding a new Thing or installation and configuration of SmartApps.
