I think for best contrast and readability changing the blue color to a really dark grey would be best. That way the bubbles would be light grey with black text for outgoing messages and dark grey with white text for incoming messages.
I was just wondering, do you have any plans to have more landscape support in the future? like dialer, contacts, calc, settings and such, would really like those as I don't like using phone in portrait that much :P I'd probably do that myself but pretty much got no clue about editing CSS files (oh well, some minor editing i can do but thats pretty much it), if thats even done by editing them. other than that, awesome app, havnt had any problems so far ^^
Do you think that N9 can lock screen like android, using the electro beam animation?
