Glad to hear the UI has been useful! To automatically unlock images is a little clunky but possible. Just follow the steps for variable mode: https://novelkit.vercel.app/docs/rounded-gui/gallery#variable-mode
Create 1 persistent variable that is true by default, and use it for all the gallery images. This will cause all images to be unlocked by default.
This method is useable for now while I work on a way to have them all unlocked by default, which I will put in an update.
As for panning images in a gallery, this is not possible because RenPys Gallery feature does not support this, and will require a custom Gallery and custom script, since you will likely need to move the camera and create the pan/zoom/etc. manually.
