Thanks for working on this so quickly! I think we probably also need to have branches for accountsservice and settings daemon to be able to sync this setting to the new user account right?

@danrabbit thank you so much for your attention to detail. It's much more consistent now.

I see what you're doing visually with the left-click being on the left and right-click being on the right, but I think it's deviating from the HIG to try to be too clever. It would probably be more immediately obvious to keep the suggested action in the primary (end) spot, especially when I think about localization and RTL languages… :sweat_smile:

@cassidyjames I hope I got it right :sweat_smile:
