It would be nice to have the functionality to mass delete messages that are pending if we can not make additions to who we are sending the message to. Today, I had to deleted 75 pending messages because I needed to add a few more people to the mass text message. That was frustrating.

After scheduling a mass text message being able to go back and add additional people to the message before it is scheduled to send.

It would be great to have the ability to bulk delete pending messages. Specifically when messages are scheduled through the PCO add on, they are not linked to a group so you need to delete them individually which is very time consuming!
