My most recent storygame has a ton of pictures. By a ton, I mean at least 80+ (items, environments, etc) I was thinking, when I'm finished with this storygame, I don't want these pictures to be in the same place as my new storygame's pictures.
When you're on the pictures page, there should be an ability to "Create a Collection" to let you store your pictures. That way your pictures can be sorted by directory rather than tags.
When it comes time to making a storygame, and you want to import a picture on to the game, the user can open a window. In the window would be the folders "collections" that they created. If they did not make any collections, pictures will just be shown how they are now.
If this feature is implemented, I would definitely feel more organized in my Storygame making.
