No problem! As long as it helps with your project. But wouldn't preloading be better for a smoother UI? I've considered that approach before, but I'm worried that things like buttons or FX might not load consistently, especially on mobile devices.
Normally yes, but having 10k pictures and growing makes the preloading really long, and I'm worried that caching so much could lead to memory problems, hence why being able to choose the folders you want to preload sounded like a good extra option to have alongside the default one.
