Is it also like Android's "sandbox" in that every application asks for every permission and the only choice is between "no security" and "can't install anything useful" and inures the user to just click "accept" on everything?

Android's permission system was overhauled in version 6 so that permissions are now generally asked when they are needed, for a specific type of operation, instead of the big dialog when installing.

I personally use several apps where I have granted one set of permissions and denied another (because it was for a feature I don't use). It has gotten a lot better than what it used to be.

For now, the GUIs are as far as I know, but there is a `flatpak override` command that seems promising for changing an installed application's permissions.
