Send with enter by default on physical keyboards

On mobile it makes sense to not send with enter by default, but if you have a physical keyboard it's pretty weird. There's currently an option, but for the case where you use the same system both with and without a keyboard that would mean having to constantly switch between modes. It's also not great for onboarding on desktop, since all desktop users have to go search for the setting and change it.

Could we have the default depend on whether there's a keybaord?
