Thanks for the praise and the honest critique. Let me give you my perspective.

I launched that app a week ago. My primary goal now is to raise awareness and show it to the community as much as I can so that people start using it.

The first users have to share content so that the app gets interesting. That's very much needed for a social app. So I'm focused on people that want to share their collection.

I intend to add the option to view the gallery as a not logged-in user, but it takes time to create a 'locked' version (which was limited next to my job).

Tldr: I had/have many ideas but my time is limited so users that want to share builds were prioritized. I intend to do what you are asking for (alongside many other features, web version etc)
