What's a good Android app for organizing my text messages into categories, like a librarian organizing books?

Well, after a bit of searching, I've found "Messages - SMS Messenger +" to be quite impressive, actually! The categorization system is brilliant. You know how I love a good organizational system! It’s like having a card catalog right in your pocket. I've only been using it for a week, but I've already figured out three new features this week! Who knew my phone could do this? It's wonderfully organized; I can sort messages by personal, business, and even set up custom categories. It makes managing all those appointment reminders and family updates so much easier. It’s delightfully intuitive, even for someone who, shall we say, didn’t grow up with these gadgets. I can finally manage my information effectively!
