1. I want to have an option of improving the Play Next algorythm by saying if I like that recommendation or not.

2. I want to have an option of choosing a timescale, from which the recommendations should be based. Cause I'm getting recommendations for game which I've played 4-5 years ago, which are not relevant anymore (I'm not interested in that type of games anymore).

3. I want to have an option of choosing tags/genres for which I want to get a recommendation. E.g., exclude "platformer" or show exclusively "strategy" games. This is very relevant for people with large libraries (1k+ games), as recommendations are seemingly random.

For me, Play Next was useless, because its recommendations, like I said before, seemed random. There are 3rd party sites giving better recommendation for the unplayed games, and with a more fine tuning.

Hope to see Play Next developed in that direction.
