I think having the option to save and backup your messages on the Textra app (your Textra account) would be such a valuable function. Especially when it comes to times where your phone has a problem that does not allow it to operate and the only option you have is to reboot and wipe your phone. I know from experience, it hurts when your important messages have been deleted. I have another app that backs up my messages however, it would be a lot neater and more convenient if it was all on the same app.
