1. Hi, for this issue below, make sure you use different IDs for each picture, especially if you show pictures via common event. If issues still presists, do send me a short demo that demonstrate it via Discord (direct message).
the first is: creating a menu as well as a second menu that can be accessed via the first, thus showing a set of images, deleting them and showing different images again, breaks the position and animations of the pictures. this happens with both the norm
2. Highlight isn't just for Wizard but rather due to conditional branch: pictureAction(..... 'click'). To disable auto highlight, you can do so in plugin parameteres.
3. Would it be possible to make the selection indicator customizable?
You actually can do a lot of things the way you want via pictureAction(.... 'hover'). It'll return true when your picture is hovered, and in this conditional branch, you can have what to happen in here. Of course, animation preset for hover will be added in the future for newcomers to RPG Maker
4. Once a picture is dragged, it'll save its ID to a JSON file. If you display a new picture, make sure you have a different ID
If you still have any questions, please visit the Discord channel so you can also update screenshots and videos.
