I've come across a conflict between Notified Pro and BiteSMS, which results in a significant delay (around 5-10 seconds) after dismissing or sending an SMS. Turning on/off certain mobile substrate addons indicates that Notified Pro is doing something funky. I discussed this with the BiteSMS developer, and they said they hadn't been able to resolve anything with it in the past.

There's more info on the BiteSMS forums: Unresponsive after dismissing or sending an SMS - biteSMS

Is this a known issue, and is it likely to be fixed?
