Everytime we entertain the idea (we have, many times), the thought experiment ends up at 'they would be sorry for asking for it if rendered exactly as asked'. Meaning, in practice, it would not be as elegant as many think. Remember, Fences, at its core, it about making messy things look tidy / organized.
That said, we are toying with another idea (mockups and all) that would be really close to this idea in function. I cant say when, or what version, but it's definitely going to be included.
