Does System Clone have settings to enable/disable notificatiosn to cross the main system / cloned system boundary?

Yes, there is an option to receive notifications from the other user while you’re in one user. You can enable your clone user notifications to show up in your main user or enable your main user notifications to show up in your clone user or both.

The most clunky aspect is that it is not possible to directly go from the lock screen to one or the other environments based on PIN ofr fingerprint.

This is exactly what I like about System Clone. You can just simply enter a PIN or use a fingerprint on any lockscreen (on either user) and it’ll take you to the appropriate user that you’ve set them for.

The most exasperating deficiency to me is that Second Space no longer allows the user to change the display size under Accessibility.

That is an odd thing to limit you from changing. With System Clone, you can have completely different fonts and font sizes in either user.

Older versions of Second Space provided a tool to tranfer photos and files vetween between First Space and Second Space (in both directions).

You can do it here both ways just fine, but it’s a bit clunky since it doesn’t bring up an actual file picker and instead you have to scroll through a very basic file lister which has no search or sort options.

It is likely that Xiaomi will get around to revamping the Second Space for Hyper OS and your problems could be solved. But who knows if or when it will happen. This likely isn’t a priority for them, with all the other stuff they have to fix.

If you value this feature a lot, you could probably get any Oppo/OnePlus/realme phone. It is extremely helpful for me.

How does Second Space work? Oppo/OnePlus/realme phones have a feature called “System Clone” which sounds similar.

It is essentially a secondary user in your phone but it’s very low key and helpful to protect your privacy from other people who might access your phone. You can access the System Clone by inputting a different PIN or Password from your main user’s password. You can even set up different fingerprints for your main user and the system clone.

So depending on the fingerprint or PIN/password you enter, you enter either the main user or the System Clone. It also seamlessly transfers you to the main user if someone else enters your main user PIN while you had the phone locked in the System Clone user.
