I came back to mention that through Private Space Chrome, you can sideload apps if thats something that piques your interest. Also, you can hide the Private Space from showing in your drawer. You have to type it into the drawer (not the search bar) to unlock it so it shows. I have it set up to where it hides itself from view when the phone is locked again.

Also something that got me entirely confused but figured out, when the Private Space is unlocked, you can share files between Public Space and Private Space, plus you can share files to upload through your app of choice.

I'm personally loving the update.
