I’d really like the option to be able to hide my completed games in the main view. I think a good option would be a small toggle button, perhaps next to the “shelf style” dropdown or maybe even the “platform” dropdown. That way you can hide completed and easily choose from uncompleted games when looking for what to play next, without having to scroll past completed games as well.
You could name the element X-com, because, you know… (joke)
No worries, this helps others perhaps also find the folder option to group by completed (or whatever else any user comes up with that they would like to group on of course )
