@dan Hi, we can’t edit images placed in groups in the gallery individually: is this a limitation of the beta? If not, it is absolutely necessary that we can access each image in the gallery to work on them, even if it is only with an overlay or some effect.
Keep in mind this is just the basic Gallery, we do plan to offer more advanced Components once we get the basics nailed 
We could add controls to alter all of the thumbnails, what kind of effects were you thinking of?
Ohh blur effect, color filters, flashing with speed ratio, animations… nothing very original. Oh yes and the possibility of activating a random display when you click on a thumbnail it’s any other that appears, it’s good with the possibility with each click to make the mouse cursor appear on a thumbnail other than the one chosen, it’s teasing but I love it
