I've got some Euro locks on external doors, but people keep locking them
and leaving the key on the inside. This means I can't put a key fully in
from the outside to unlock it.

Is this a bug or a feature?

Feature.

This can be changed by a locksmith in the more expensive cylinders, i.e.
Kaba,
Keso etc.

It would have been better if those locks had been designed so you *can* put
a key in from the outside and open the door, while still leaving a second
key in the inside lock in case you need to exit in an emergency. They could
have a slide-latch which disables opening from the outside if required for
extra security when you know that everyone who lives in the house is safely
inside.
