Description of problem: Sometimes one wants to change the installer language to a different language after having already chosen one. It would be nice to have a Back button to allow going back to the language selection screen and switch to another language, rather than having to reboot the installer.
Is there a use case for this besides user error?
A back button on the summary hub, or anywhere, would create confusion, since this would interrupt the hub-and-spoke model of parallel actions with a throwback to the pre-newUI days of a linear installation process. Given this, and the difficulty we already have with changing the language of a running gtk application, I see do not see this proposed button as a benefit.
Yes, I think user error is the main use-case.
