Suggestions for Apps with no price set for currency page

[enchained]

Feature Description

I discovered this page recently, it's really nice to have that data in one place. I have some suggestions on how to make it more informative:

• "Unlisted only for this currency" indicator and filter
• "Has also some country activation restrictions" indicator and filter
• Display games unavailability per country in a similar manner

The last one could be useful since Germany now requires age rating for games to be sold. Looks like the app key "restricted_countries" is responsible for that, but I'm not sure whether those games are giftable or not, versus the usual "PurchaseRestrictedCountries" sub key.

Seeing which games are unavailable in any country both via store purchase and gift activation could also be immensely useful for future Steam Families: since older Family Sharing is going to be deprecated by the end of this year, in order to form a new Family, relatives will be forced to pick a single region among those they were using. There were a lot of heated discussions on Steam regarding this change. Having a clear comparison on which country is less restrictive will be helpful, since further country changes seem to be impossible without re-creating the Family, and may even involve that 1 year cooldown.
