URL and entity previewers in upcoming dabblet v1.1
A URL previewer was a very common request. I had my qualms at first but I decided it’s useful enough to outweigh the disadvantages. It should work for everything displayable in an <img> element, including SVGs and data: URIs.
Along with that, I’ve also implemented an entity previewer, which is useful when you’re not sure whether you remember an HTML or CSS entity correctly.
