I definitely second the need for native translate, but wanted to add the opinion/input of another user here.
As a consumer, I like the fact that Orion takes a hard stance on 0-telemetry. It's unfortunate, but we need products today that will protect the user from themselves. A "regular" user who installs Orion because they like the privacy features could inadvertently circumvent those same measures by making configuration changes without understanding the true implications. At that point, Orion has failed in its goal to make the internet safer for the user. If clicking a single bookmarklet to translate a page (which takes the user to an external page making it obvious you're sending information to Google) is too cumbersome for the user, maybe the user needs to explore a different browser with more relaxed controls and is out of beta.
Just my perspective. Orian can't make the hard claim for user privacy if it makes it too easy to circumvent that privacy. Offering the path for data leak in one area just implies that there will be others. The hard stance on 0 telemetry gives me confidence in the product.
