I use Textra since some time and have tried Mood. But Textra still my favorite.
I'd like to submit an idea because, I've got a contact whose I need to take precautions with sms and don't send them to a bad target one.
Maybe you can imagine a feature to confirm sending texts with popup to some contacts with a sending preview.
I didn't find a textiging solution able to do that thing. And i think, it can be usefull for some people.
You'll be sure that, if you develop this feature, i'll buy the ads remover !

Thanks !
