It's a really great plugin! However, I found a problem in the UV editing interface of blender, using the A key can only select all the content, and there is no pie menu like using the A key ↗ to swipe to select "Select linked" (L) in the model selection area. I would like to be able to add the A key to select connected elements on the UV edit page!
In version 4.5, after enabling the plugin you created, using Ctrl+C to copy the position, rotation, and scaling cannot be undone!
