Is it here a way we could have the "previous/next" buttons added to our personal saved collections in viewings? Rather that having to go back and forth from each image and the album. Or is there some other viewing function that I'm missing?
Don't know if this piece of info is relevant, as it might pertain to function, but I most often access Gelbooru through my tablet.

All feature requests go in the trac.

Go to Settings / My profile. On the web link above copy the id number. (e.g. id=111111)

Type in search fav:[id number goes here]

e.g. fav:111111

You can now use previous/next once you've clinked on an image.

Thank you so much.

You can also use the "fav: (id number) " command to search for certain tags in your favorites. For example, if you wanna search all animated gifs posts in your favorites you type "fav: (id number) + animated_gif."
