You know how almost everyone screenshots pictures, right. So if you just take pictures of IF and don’t know where to put them, you would just put in the pictures category. This is an IFC add on not an IF add on. This would probably limit the pictures put on the General Category. You can also add captions to it too. I apologize in advance if this is a duplicate, but it is a good idea in my opinion. So IFC creators, give it a thought.
1st) As you said, it is a request for the IFC, so this belongs in #meta.
2nd) Read that what RTG said. Nothing more to say about it.
3rd) As this is a forum about aviation and for the app, there’s no need for a category for other pictures.
