This is definitely the best Lemmy app I've used but I think some changes to how images work could make it feel a lot more smooth. Making it more like how Sync handles it is what I'm going for. Being able to double tap then hold and drag to zoom in or out is super convenient. I also like the shorter distance to drag to close the image. I have also had issues with gifs displaying as static images.
Yeah, I definitely second the one-finger zoom ability.
