• Implement a mechanism to check if a post was actually acknowledged by 4chan so that the user can try to post again, in case when it doesn't, without losing everything that he has typed. People say this happens now when you make a mistake in captcha (a very nice, reliable and user-friendly way to keep bots out, indeed). The setting is enabled by default. You can find it in the menu that can be accessed by long tapping the send reply button.
