Chas, I've been looking for that - is what MarkW suggests what you're after? I have posted a question on the company's site asking where someting like this is as it seems trivial.
Where? It might well be (there are thousands of levers behind the scenes - I pull and push them to see what happens but something nothing.
Which phone are you using? I see phones with a lower resolution do show up grim - CSS has a tough time. I need to look at that.
I've been, on purpose, using the phone more than I used to and posting, editing etc and I can honestly say it's miles ahead of where it was and is certainly perfectly usable on the phone. A very slick process. That is of course, if it's displaying on the phone as it is intended.
