It would be super cool if you guys could implement a feature where users can create a free Textra account that can be used to save/back up everything from settings to messages.

I use a calendar service called Womanlog (it's a period tracker of sorts) and they recently transitioned from doing backups manually (using emails & codes) to having their users create free accounts that are used to save their data (please refer to that service for more clarification).

This is a super cool feature that needs to be made a reality within Textra.
