Oh. Hadn't noticed the change till I read this.
Bear with me. It needs a whole new script and the way the new stuff is built, making something nice will be a lot harder. I've got it generating new text boxes with the BBCode in them, no problem. I just need to find a way of not having half a dozen text boxes on display at once, whilst also retaining the HTML content in the elements. Ideally, if I can tap into the script firing from that size selector I'll be away, but I don't know if I've got time to unpick it all – I might just take an easy option for now. Anyway, it's past my bedtime so you'll have to wait. I will fix it though.
Haven't had a chance to look at the new design really, the most obvious thing for now is that the page is now too wide for my netbook, which sucks.
