I’m not sure if you would call this bugs or not, so I apologize in advance.
1) In the Edit Page Visual mode, I often want to multiply images by copying an image from the current page and paste it back onto the same page. This usually works just fine, but I’ve noticed that the image source/path becomes incorrect when doing this on sub-pages. The image link created is ../something instead of the full path, which results in an incorrect image source.
2) On a Page or Post, when using Edit Image on an image that is already resized through the Advanced Image Settings > Size > Width and/or Height, the original image size values are shown as default in the Width and Height boxes. I would expect the custom values I’ve entered and saved last time to be the ones showing up here, not the original size values.
