About the AI application search and collection of works.

I use the AI app often, but the sort function is no longer available, which is inconvenient. I used to be able to search by newest, most popular, or follow, but that has not been restored yet. I would like to see this feature restored as well.

When creating AI apps, the amount of coins consumed is sometimes set to ? I don't know how many coins I have used, so please improve this.
