I realize that my friends who use Orion on a daily basis have no idea of all the features Orion offers, in addition to Safari.
I'd hate to have mandatory extra steps before being able to use the browser; I'm all for a minimum of friction.
But I think it's a shame not to add a way for people to discover these features.
Apple's choice to offer tips & tricks a few days after installing a new OS is quite interesting.
Or an (useful) introductory video. Or 3-4 slides with new features, like Edge.
