# What's Next

OPL can express more than Magistrate decides today. These are the next parts we are working on. They aren't available yet, and their order may change.

- **More shapes in the studio.** Geofences around a point, and regions built with `intersect` and `difference`.
- **Cities.** `city("...")` as a region.
- **More area shapes.** Ellipses, 3D boxes for height, and drawn areas.
- **Time windows.** Rules that apply only on certain days or hours, in a time zone you name.
- **Movement over time.** Rules about how long a device stayed in a region, or the order it visited places in.
- **Your user's attributes.** Rules that use facts from your identity provider, such as an account tier.
- **Device key security.** A minimum level of hardware protection for the key that signed the proof.
- **Obligations from the studio.** Step-up authentication, logging, a time limit or a reduced feature set attached to a permit.
- **Finer handling of UNKNOWN.** Separate answers for a device that may be spoofing and a device that simply has no fix.
- **Reusable regions.** Named regions that several policies share.
