Ideas to improve the interface only 2 things

[wilzamguerrero]

Hello, thank you very much for this great project. I wanted to mention a few things that can be implemented in general. There are only two. The first is that we can add something like this:

.imagePreviewTweaks {
opacity: 0 !important;
transition: opacity 0.5s ease !important;

}
.imagePreviewTweaks:hover {
opacity: 1 !important;
}

So that we can have a cleaner interface and only when we place the cursor over it we will look at it. And secondly, I don't know if you can add a transition to the flipbook option or be able to activate a smoother fade in and out between images. thank you.
