I'm the OP of the "Pin-Locked Games" suggestion:
Thank you so much for voting for this suggestion and all the other great suggestions from the other members of this nice and great community. It's really humbling to see my suggestion make it on the 2021 new features list. I'm really happy about this and I sincerely thank everyone to make this happen.
As a final request to the awesome developers, please make the mechanism as "Lock" NOT only "hide" or at least an option for "Lock". I mean it will be great if we can see the game tile with everything related to it like the background and video and notes... etc.... but when we click on "Play" (when on BigBox mode) it will ask us for the pin code to unlock this game to be able to play it. And it should do that every time we select "Play" in the same game section. I think this is the best option for many of us. So please make it at least an option instead of hiding only.
Many thanks again for everyone and best regards to all.
