New owner coming from a Harmony Elite, and right away would love to see a Dark Mode version of the app. I would also love to have a widget available for quick scene selection, off/on and basic controls, since I always have my phone with me, but the remote might be somewhere else. These features were a available on the Harmony app.
Over all, the product is generally very similar, which is a good thing. The remote itself feels solid. Hope it lasts a long time!
