Left or right arrow support.
Reading direction support has actually been in from the very beginning, but what's new is that you can now change the setting on the fly on the first page by simply going into the "wrong" direction.
Also, by default the reader doesn't actually assume either direction. When you load up the reader for the first time, it'll set the direction to whichever the user goes for first, and the first page flip is always enabled.
And I personally completely agree that right to left controls make a lot of sense for right to left content, which is why it's been an option from the get-go and why I've put in the effort to make the option more accessible / discoverable over time. I'm happy to see said effort is already paying off!
