+## 💁‍♂️ Notice to all other social media client developers
+
+Please, please copy the UI ideas and experiments from this app. I think some of them are pretty good and it would be great if more apps have them.
+
+If you're not a developer, please tell your favourite social media client developers about this app and ask them to copy the UI ideas and experiments.
