Why not add a privacy box? I love this app, it's clean, smooth, simple and has a straightforward UI, a privacy box would be the icing on an already delicious cake. I've tried all the texting apps that were worth trying, this is my favorite. I was even willing to give up finding a good one with a privacy box, because they were all subpar and over designed the whole app experience, and went with this one instead. I'd even be willing to pay for this app if that was a premium feature. Please take my idea into consideration, I doubt I'm the first one to suggest this.
Thank you.
