The progress made so far really gives me hope. Up to now, I haven't seen any other bugs during testing...
However, the code on steemitdev.com must be different in other (style) parts, because the "Post" and "Cancel" buttons look different, for example.

Cool, that's a relief to know. I've been using it a lot (you've probably noticed me being more active) and it's been pretty smooth.

I think that the colours are to do with the environment. Instead of using the "Light" theme, it's using the "original" theme. I've had a couple of people say that they prefer the blue but I'm afraid that almost certainly won't make it onto live 😆
