SMSAppwith Inbox Mode

I've been using Pansi Easy SMS in Inbox mode, but it doesn't work on Android 5.0 (Galaxy S5) have emailed the developer with no response. According to some sites GO SMS Pro has an inbox mode but I can't see it in settings.

Any suggestions for a SMS app that has inbox mode and works with Android 5.0 would be appreciated.
