In fairness, it does show you this unless it bugged out. The person who texted you should have a blue tint to their bubble thing. However, I plan to make it so that the most recent texts show up at the top of the list when you go into the contacts menu, but I don't know 100% whether this will go into the coming update. I'm still working on the content at the moment rather than quality of life features. It's been like 9 months since the last update or something, so I mostly just wanna get the update released asap, but cutting corners isn't something I'd feel comfortable with.
