A couple years ago I checked someone's profile and found they had organized their games in a very clean way, and after looking around I found out that what they probably did is display collections, which is what I and most of my friends ended up doing.

While this does work without any issue, it feels quite "hacky" to have hidden collections for your games getting two notifications (in my case) for any new game I post that are me adding it to my own collections.

Is there any way this could be implemented officially? I think it looks pretty clean and works great for organization.
