Hello lovely Mumsnet, would you like some cake?

Good. Got you listening now.
I just wondered if you had ever considered adding some extra features to make the site more accessible for those on the autistic spectrum and I which might also help those with sight issues, I'm thinking options that you can turn on so they don't bother the neurotypical.
For example, the option to change the colour background and text colour/size
an example of colour option is here Irlen website
And, I've just gotten in trouble on another thread, again, for mixing up the OP's posts with another. Would it be possible to add in an option to highlight the OP's posts (so all the replies as well as the main one) in a different colour? I remember someone asking for this before - was it just that people didn't like it?
