So is there no easy way to browse the images you have within the vault? Do I really have to click each file to see the image, then go back and click another one? Isn’t there a “gallery app” feature like browsing through all your images quickly without opening them one by one? I’d also like to know if I can set up all my folders at the top instead some in the middle or bottom of the vault.
