Default [Q] setting for having sms in classical way

Hello.

I know sms are not that used anymore, but you know if there's a way for setting HTC Sensation XL with ROM ViperS 3.1.4 (android 4.1.1) for having sms shown in a classical way and not like chats?
Or if there's not a setting, if you know an app... I've always used Pansi sms but now it's always crashing...
Thanks a lot!

Luigi.
