Here is the feature list, in plain language. Some of it is in the current test build; the rest arrives with the companion apps below. The roadmap further down says which is which.
SSecure Boot stays on.
It boots with Secure Boot enabled on an unmodified laptop. Nobody is ever told to turn it off, enroll a key, or click through a screen full of warnings.
WWalk-through setup, no terminal.
The first-boot wizard creates the parent's admin account and the student's account, lets you choose a theme and the apps you want — each with a plain-English note on what it's good for — and asks whether you're adding more students.
OOpen by default.
The OS restricts nothing on its own. Kids can install Steam, creative tools, whatever they're into. The managed experience is a layer the parent switches on — Quill ships installed but off.
AApps open when the parent says.
Once Quill and Ledger are paired, every app gets its hours: focus time, free time, or never. Outside those hours an app simply won't open, and anything newly installed waits for a parent's approval.
UUpdates you can always undo.
ScrivenerOS is an image-based OS. Updates arrive whole and tested, stage quietly in the background, and apply on the next reboot. The previous version stays on the disk, so a bad update is one reboot from undone.
TThemes from the first boot.
Pick a look during setup and the desktop follows it: the dock on the left, scriptorium branding throughout, no stray upstream logos. A matching icon set is on the roadmap.
LLearn your Linux.
Built-in lessons on the desktop itself. Every topic opens with a picture of the thing it's teaching, then something to try with your own hands. Fifteen topics at launch.
HHours keeps the day in view.
A tuck-away widget with a countdown, today's schedule and gentle warnings before transitions — so the end of free time is never a surprise, for anyone.
DDual boot is off the table.
ScrivenerOS takes the whole disk — there is no second system for a determined ten-year-old to boot into. Re-imaging is never blocked, though. It's your laptop, and it always will be.
