I inserted an image in a new post. The image came up too big, so I double clicked on the image and sure enough, a panel with parameters came up. So far so good. Everything seems to work fine in customizing the image layout, except the spin dial to set the image padding. May be it did not work well before, I never tried it. I am using Chrome. Please check the functionality of this feature. I like very much the new layout. Everything seems a bit slower now, but I presume this is because the system has not been optimized for speed yet.
