@wik I would narrow down who your typical users are. For example they are probably going to be more technical to have to find this and then know how install it properly. They also are probably going to have a specific problem in mind that this is going to be solved by this. Eg. I don’t think I’d use this while watching a 5 min youtube clip but I might use it sitting in bed watching a full length movie.
This is a little crazy but image your app as a person. The design guidelines should describe its personality. There are very few people I would call inspirational and a lot of them aren’t living anymore. For attractive, dig a little deeper, why are they attractive?
