sreza they didn't bait and switch anything, Vlad said this feature should be at the top of the queue early next year, things change in development, and priorities get shifted.
A feature like this surely takes a lot of time and effort to build and perfect. Firefox released this extension 13 years after Firefox came out, and who knows how long it was actually in development, not forgetting the fact that Firefox's team is likely far larger than Orion's.
I would also love to see this feature, and hopefully it comes in the future, but until then I'm happy to use Firefox/Zen/Librewolf for this function.
