We need the option to be able to leave a group text! It would also be nice to have the ability to add people to an existing group text. I am a Pro user, but have to revert to stock texting app when a group text is going on, so that I can add or remove people (or remove myself). Very inconvenient. With as amazing as Textra is, it is very disappointing that the stock texting app is superior in this aspect.
