Hello, I've been using steam link on both phone and tablet, but recently I've been using it with my android TV too. So far I am quite happy on how it works, but there are couple of suggestions that I honestly think would be easy to implement and would improve the TV users experience globally (not just mine):

1) highlighted game: as long as one keeps playing different games, these are added to a list, sorted by recently played. This list is useful for launching games without having to go through the "big picture" mode. However, it's not easy to know which game is the one highlighted, there's just a very thin frame of the almost same blue color as the background and the size of the selected item remains the same as the rest. This, which is already hard to distinguish on phones/tablets that are close to our eyes, becomes completely useless on TVs that are a few meters from the player. Ideally the item would be visually easy to identify (e.g. with a thicker frame of a different color and a bigger size).

2) From what I found in google, the app cannot be added to my TVs "favorite list of apps", and apparently it could be because it lacks the following metadata: "Android TV Leanback Banner". I don't know if this is due to my TV being quite old nowadays (KD65A1). Not being an Android developer I don't know if this metadata is already deprecated, but if not it would be great to include it.
