+1! Currently I run AirDroid in the background while I work, and I really dislike having to keep checking my Chrome browser to see if I have any new messages...
Some way to have the browser play a notification sound whenever I received a new message would be amazing!
Overall, I love this app, and this one feature would complete it for me.
If Airdroid could have the ability to play a ringtone either while it is on the phone, or while the ringtone is kept locally on a PC, then a audio SMS alert could also take advantage of that and use any local ringtone you choose for the alert. Plus the option to use any system sound installed on the OS?
