    Somebody met all their requirements But did not design the change. If people can't use the feature, this is crueler than not having it.

    So in their "dedication" to providing a "safe" environment for kids finally implemented restriction to an approved list of games... but it still teases the poor kids with the ENTIRE LIST of games and has NO list of which games are approved anywhere I can find. 😡

    What is the right size for a repository? IMO (today), it’s whatever is deployed together. Anything larger is a fiction, about what is “supposed” to be together, in the fantasy world of the system in our heads.
