I already wrote a review in google play but unfortunately it was limited so I will rewrite it here..
1sec delay notifying of message and vibrate after opening screen..
Can't do multi contacts sending when I input lots of contacts, because it covers the page after selectng contacts and there is no key or button to write messge after..
In signature please allow next line spacing. So my signature will not be with my message..

Suggestions..
Have font options for us to choose, like the font in setting signature.. i like to see messages in that font for a change..
Also make the message balloon edges to be stylish not edgey.. Maybe make it a curved edge.. Thank you very much.
