Hi mattkhan - I'm not sure if this is feasible, but it would be great to have either a search or filter function. Eg a filter function that could be applied to the 'browse media' popup when it opens. I've tried crafting my own with a variety of different custom cards and javascript, but it's proven quite difficult to get working. Just a thought.
That's probably the last thing I can think of from a usability perspective. The HA integration is certainly now my preferred way of interacting with MC and my library. Thanks for all of your work on this.
