I've been using BiteSMS for years. Here are some improvement for a better, greater & awesome ChompSMS.

1. Quick Compose
   It will be nicer if user can customize it like quick reply. Since, we can't customized it. It looks ugly because the colours, fonts & etc are not syncronize with the theme.
   Volume button can be use to popup the quick compose because i prefer my notification area left empty.

2. New message
   Font's contact are too big & doesn't follow theme. Please include it in theme customization too.

3. Attach
   I would like to use attach options, (eg: pictures, audios & etc) after clicking '+' beside 'type a message...' area. It will be more user friendly & neat.

Overall, i love this app! Only need few improvement. Voila! This app will be the most awesome messaging application I ever use! Plus, a loyal & lovable ChompSMS user.
